DESCRIPTION
    The Set-ItemProperty cmdlet changes the value of the property of the specified item. You can use the cmdlet to establish or change the properties of items. For example, you can use Set-ItemProperty to set the value of the IsReadOnly property of a file object to true.

    You also use Set-ItemProperty to create and change Registry values and data. For example, you can add a new Registry entry to a key and establish or change its value.

PARAMETERS
    -Credential <PSCredential>
        Specifies a user account that has permission to perform this action. The default is the current user.

        Type a user name, such as “User01” or “Domain01\User01”, or enter a PSCredential object, such as one generated by the Get-Credential cmdlet. If you type a user name, you will be prompted for a password.

        This parameter is not supported by any providers installed with Windows PowerShell.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

        Specifies those items upon which the cmdlet is not to act, and includes all others.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Filter <string>
        Specifies a filter in the provider’s format or language. The value of this parameter qualifies the Path parameter. The syntax of the filter, including the use of wildcards, depends on the provider. Filters are more efficient than other parameters, because the provider applies them when retrieving the objects rather than having Windows PowerShell filter the objects after they are retrieved.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Force [<SwitchParameter>]
        Allows the cmdlet to set a property on items that cannot otherwise be accessed by the user. Implementation varies from provider to provider. For more information, see about_providers.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

        Required?                    true
        Position?                    named
        Default value
        Accept pipeline input?     true (ByValue, ByPropertyName)
        Accept wildcard characters? false

    -LiteralPath <string[]>
        Specifies a path to the item property. The value of LiteralPath is used exactly as it is typed. No characters are interpreted as wildcards. If the path includes escape characters, enclose it in single quotation marks. Single quotation marks tell Windows PowerShell not to interpret any characters as escape sequences.

        Required?                    true
        Position?                    1
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -Name <string>

    -WhatIf [<SwitchParameter>]
        Describes what would happen if you executed the command without actually executing the command.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    <CommonParameters>
        This cmdlet supports the common parameters: Verbose, Debug,
        ErrorAction, ErrorVariable, WarningAction, WarningVariable,
        OutBuffer and OutVariable. For more information, type,
        “Get-Help about_CommonParameters“.

INPUTS
    System.Management.Automation.PSObject
        You can pipe objects to Set-ItemProperty.

OUTPUTS
    None or System.Management.Automation.PSCustomObject
        When you use the PassThru parameter, Set-ItemProperty generates a PSCustomObject object that represents the item that was changed and its new property value. Otherwise, this cmdlet does not generate any output.

NOTES

        The Set-ItemProperty cmdlet is designed to work with the data exposed by any provider. To list the providers available in your session, type “Get-PSProvider“. For more information, see about_providers.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Set-Itemproperty -Path c:\GroupFiles\final.doc -Name IsReadOnly -Value $true

    Description
    ———–
    This command sets the value of the IsReadOnly property of the final.doc file to true.

    The command uses the Set-ItemProperty cmdlet to change the value of the property of the final.doc file. It uses the Path parameter to specify the file. It uses the Name parameter to specify the name of the property and the Value parameter to specify the new value.

    The $true automatic Variable represents a value of TRUE. For more information, see about_Automatic_Variables.

    The file is a System.IO.FileInfo object and IsReadOnly is just one of its properties. To see all of the properties and methods of a FileInfo object, pipe the file to the Get-Member cmdlet. For example, “final.doc | Get-Member“.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Set-Itemproperty -Path HKLM:\Software\MyCompany -Name NoOfEmployees -Value 823

    C:\PS>Get-Itemproperty -Path HKLM:\Software\MyCompany

    PSPath        : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\software\mycompany
    PSParentPath : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\software
    PSChildName : mycompany
    PSDrive     : HKLM
    PSProvider    : Microsoft.PowerShell.Core\Registry
    NoOfLocations : 2
    NoOfEmployees : 823

    C:\PS>Set-Itemproperty -Path HKLM:\Software\MyCompany -Name NoOfEmployees -Value 824
    C:\PS>Get-Itemproperty -Path HKLM:\Software\MyCompany

    PSPath        : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\software\mycompany
    PSParentPath : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\software
    PSChildName : mycompany
    PSDrive     : HKLM
    PSProvider    : Microsoft.PowerShell.Core\Registry
    NoOfLocations : 2
    NoOfEmployees : 824

    Description
    ———–
    This example shows how to use Set-ItemProperty to create a new Registry entry and to assign a value to the entry. It creates the NoOfEmployees entry in the MyCompany key in HKLM\Software key and sets its value to 823.

    Because Registry entries are considered to be properties of the Registry keys (which are items), you use Set-ItemProperty to create Registry entries, and to establish and change their values.

    The first command uses the Set-ItemProperty cmdlet to create the Registry entry. It uses the Path parameter to specify the path to the HKLM: drive and the Software\MyCompany key. It uses the Name parameter to specify the entry name and the Value parameter to specify a value.

    The second command uses the Get-ItemProperty cmdlet to see the new Registry entry. If you use the Get-Item or Get-ChildItem cmdlets, the entries do not appear because they are properties of a key, not items or child items.

    The third command changes the value of the NoOfEmployees entry to 824.

    You can also use the New-ItemProperty cmdlet to create the Registry entry and its value and then use Set-ItemProperty to change the value.

    For more information about the HKLM: drive, type “Get-Help Get-PSDrive“. For more information about using Windows PowerShell to manage the Registry, type “Get-Help Registry“.

    ————————– EXAMPLE 3 ————————–

    C:\PS>Get-ChildItem weekly.txt | Set-Itemproperty -Name IsReadOnly -Value $true

    Description
    ———–
    These commands show how to use a pipeline operator (|) to send an item to Set-ItemProperty.

    The first part of the command uses the Get-ChildItem cmdlet to get an object that represents the Weekly.txt file. The command uses a pipeline operator to send the file object to Set-ItemProperty. The Set-ItemProperty command uses the Name and Value parameters to specify the property and its new value.

    This command is equivalent to using the InputObject parameter to specify the object that Get-ChildItem gets.

    <CommonParameters>
        This cmdlet supports the common parameters: Verbose, Debug,
        ErrorAction, ErrorVariable, WarningAction, WarningVariable,
        OutBuffer and OutVariable. For more information, type,
        “Get-Help about_CommonParameters“.

INPUTS
    None
        You cannot pipe input to this cmdlet.

OUTPUTS
    Microsoft.WSMan.Management.WSManConfigLeafElement

NOTES

        To run this cmdlet on Windows Vista, Windows Server 2008, and later versions of Windows, you must open Windows PowerShell with the “Run as administrator” option.

        The Set-PSSessionConfiguration cmdlet does not change the configuration name and the WS-Management provider does not support the Rename-Item cmdlet. To change the name of a configuration, use the Unregister-PSSessionConfiguration cmdlet to delete the configuration and then use the Register-PSSessionConfiguration cmdlet to create and register a new session configuration.

        You can use the Set-PSSessionConfiguration cmdlet to change the default Microsoft.PowerShell and Microsoft.PowerShell32 session configurations. They are not protected. To revert to the original version of a default session configuration, use the Unregister-PSSessionConfiguration cmdlet to delete the default session configuration and then use the Enable-PSRemoting cmdlet to restore it.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Set-PSSessionConfiguration -Name MaintenanceShell -ThreadApartmentState STA

    Description
    ———–
    This command changes the thread apartment state in the MaintenanceShell configuration to STA. The change is effective when you restart the WinRM service.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Register-PSSessionConfiguration -Name AdminShell -assemblyName c:\shells\AdminShell.dll -configurationType AdminClass

    C:\PS> Set-PSSessionConfiguration -Name AdminShell -StartupScript AdminConfig.ps1

    C:\PS> Set-PSSessionConfiguration -Name AdminShell -StartupScript $null

    Description
    ———–
    This example shows how to create and then change a session configuration.

    The first command uses the Register-PSSessionConfiguration cmdlet to create the AdminShell configuration.

    The second command uses the Set-PSSessionConfiguration cmdlet to add the AdminConfig.ps1 script to the configuration. The change is effective when you restart WinRM.

    The third command removes the AdminConfig.ps1 script from the configuration. It uses the Set-PSSessionConfiguration cmdlet with a value of $null for the StartupScript parameter.

    ————————– EXAMPLE 3 ————————–

    C:\PS>Set-PSSessionConfiguration -Name foo -MaximumReceivedObjectSizeMB 20

     WSManConfig: Microsoft.WSMan.Management\WSMan::localhost\Plugin\foo\InitializationParameters

    Description
    ———–
    This example show sample output from the Set-PSSessionConfiguration cmdlet.

    The Set-PSSessionConfiguration command in this example increases the value of the MaximumReceivedObjectSizeMB property to 20.

    The Set-PSSessionConfiguration command returns a Microsoft.WSMan.Management.WSManConfigLeafElement object that shows the parameter name and new value.

    It also prompts you to restart the WinRM service. The Set-PSSessionConfiguration change is not effective until the WinRM service is restarted.

    Description
    ———–
    This command shows different ways of viewing the results of a Set-PSSessionConfiguration command.

    The first command uses the Set-PSSessionConfiguration cmdlet to change the startup script in the MaintenanceShell configuration to Maintenance.ps1. The output of this command shows the change and prompts you to restart the WinRM service. The response is “y” (yes).

    The second command uses the Get-PSSessionConfiguration cmdlet to get the MaintenanceShell session configuration. The command uses a pipeline operator (|) to send the results of the command to the Format-List cmdlet, which displays all of the properties of the session configuration object in a list.

    The third command uses the WS-Management provider to view the initialization parameters for the MaintenanceShell configuration. The command uses the Get-ChildItem cmdlet (alias = dir) to get the child items in the InitializationParameters node for the MaintenanceShell plug-in.

    For more information about the WS-Management provider, type “Get-Help WSMan“.

        “Get-Help about_CommonParameters“.

INPUTS
    System.ServiceProcess.ServiceController, System.String
        You can pipe a service object or a string that contains a service name to Set-Service.

OUTPUTS
    None
        This cmdlet does not return any objects.

NOTES

        To use Set-Service on Windows Vista and later versions of Windows, start Windows PowerShell with the “Run as administrator” option.

        Set-Service can control services only when the current user has permission to do so. If a command does not work correctly, you might not have the required permissions.

        To find the service names and display names of the services on your system, type “Get-Service“. The service names appear in the Name column and the display names appear in the DisplayName column.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Set-Service -Name lanmanworkstation -DisplayName “LanMan Workstation”

    Description
    ———–
    This command changes the display name of the lanmanworkstation service to “LanMan Workstation”. (The default is “Workstation”.)

    Description
    ———–
    These commands get the startup type of the Performance Logs and Alerts (SysmonLog) service, set the start mode to automatic, and then display the result of the change.

    These commands use the Get-WmiObject cmdlet to get the Win32_Service object for the service, because the ServiceController object that Get-Service returns does not include the start mode.

    The first command uses the Get-WmiObject cmdlet to get the Windows Management Instrumentation (WMI) object that represents the SysmonLog service. The default output of this command displays the start mode of the service.

    The second command uses Set-Service to change the start mode to automatic. Then, the first command is repeated to display the change.

    The final command displays the start mode of all services on the computer.

    ————————– EXAMPLE 3 ————————–

    C:\PS>Set-Service -Name Schedule -ComputerName S1 -Description “Configures and schedules tasks.”

    C:\PS> Get-WmiObject win32_service -ComputerName s1 | Where-Object {$_.Name -eq “Schedule”} | Format-List Name, Description

    Description
    ———–
    These commands change the description of the Task Scheduler service on the S1 remote computer and then display the result.

    These commands use the Get-WmiObject cmdlet to get the Win32_Service object for the service, because the ServiceController object that Get-Service returns does not include the service description.

    The first command uses a Set-Service command to change the description. It identifies the service by using the service name of the service, “Schedule”.

    The second command uses the Get-WmiObject cmdlet to get an instance of the WMI Win32_Service that represents the Task Scheduler service. The first element in the command gets all instances of the Win32_service class.

    The pipeline operator (|) passes the result to the Where-Object cmdlet, which selects instances with a value of “Schedule” in the Name property.

    Another pipeline operator sends the result to the Format-List cmdlet, which formats the output as a list with only the Name and Description properties.

    ————————– EXAMPLE 4 ————————–

    C:\PS>Set-Service winrm -Status Running -PassThru -ComputerName Server02

    Description
    ———–
    This command starts the WinRM service on the Server02 computer. The command uses the Status parameter to specify the desired status (“running”) and the PassThru parameter to direct Set-Service to return an object that represents the WinRM service.

    ————————– EXAMPLE 5 ————————–

    C:\PS>Get-Service schedule -ComputerName S1, S2 | Set-Service -Status paused

    Description
    ———–
    This command suspends the Schedule service on the S1 and S2 remote computers. It uses the Get-Service cmdlet to get the service. A pipeline operator (|) sends the service to the Set-Service cmdlet, which changes its status to “Paused”.

    ————————– EXAMPLE 6 ————————–

    C:\PS>$s = Get-Service schedule

    C:\PS> Set-Service -inputobject $s -Status stopped

    Description
    ———–
    These commands stop the Schedule service on the local computer.

    The first command uses the Get-Service cmdlet to get the Schedule service. The command saves the service in the $s Variable.

    The second command uses the Set-Service cmdlet to change the status of the Schedule service to “Stopped”. It uses the InputObject parameter to submit the service stored in the $s Variable, and it uses the Status parameter to specify the desired status.

Set-Acl

NAME
    Set-Acl

SYNOPSIS
    Changes the security descriptor of a specified resource, such as a file or a Registry key.

SYNTAX
    Set-Acl [-Path] <string[]> [-AclObject] <ObjectSecurity> [-Exclude <string[]>] [-Filter <string>] [-Include <string[]>] [-Passthru] [-Confirm] [-WhatIf] [-UseTransaction] [<CommonParameters>]

DESCRIPTION
    The Set-Acl cmdlet changes the security descriptor of a specified resource, such as a file or a Registry key, to match the values in a security descriptor that you supply.

    To use Set-Acl, use the Path parameter to identify the resource whose security descriptor you want to change, and use the AclObject parameter to supply a security descriptor that has the values you want to apply. Set-Acl uses the value of the AclObject parameter as a model and changes the values in the resource’s security descriptor to match the values in the AclObject parameter.

PARAMETERS
    -AclObject <ObjectSecurity>
        Specifies an ACL with the desired property values. Set-Acl changes the ACL of resource specified by the Path parameter to match the values in the specified security object.

        You can save the output of a Get-Acl command in a Variable and then use the AclObject parameter to pass the Variable, or type a Get-Acl command.

        Required?                    true
        Position?                    2
        Default value
        Accept pipeline input?     true (ByValue)
        Accept wildcard characters? false

    -Exclude <string[]>
        Omits the specified items. The value of this parameter qualifies the Path parameter. Enter a path element or pattern, such as “*.txt”. Wildcards are permitted.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Filter <string>
        Specifies a filter in the provider’s format or language. The value of this parameter qualifies the Path parameter. The syntax of the filter, including the use of wildcards, depends on the provider. Filters are more efficient than other parameters, because the provider applies them when retrieving the objects, rather than having Windows PowerShell filter the objects after they are retrieved.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Include <string[]>
        Changes only the specified items. The value of this parameter qualifies the Path parameter. Enter a path element or pattern, such as “*.txt”. Wildcards are permitted.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Passthru [<SwitchParameter>]
        Returns an object representing the security descriptor. By default, this cmdlet does not generate any output.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Path <string[]>
        Identifies the resource whose security descriptor you want to change. Enter the path to a resource, such as a path to a file or Registry key. Wildcards are permitted.

        If you pass a security object to Set-Acl (either by using the AclObject parameter or by passing an object from Get-Acl to Set-Acl), and you omit the Path parameter (name and value), Set-Acl uses the path that is included in the security object.

        Required?                    true
        Position?                    1
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -Confirm [<SwitchParameter>]
        Prompts you for confirmation before executing the command.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -WhatIf [<SwitchParameter>]
        Describes what would happen if you executed the command without actually executing the command.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -UseTransaction [<SwitchParameter>]
        Includes the command in the active transaction. This parameter is valid only when a transaction is in progress. For more information, see about_transactions.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    <CommonParameters>
        This cmdlet supports the common parameters: Verbose, Debug,
        ErrorAction, ErrorVariable, WarningAction, WarningVariable,
        OutBuffer and OutVariable. For more information, type,
        “Get-Help about_CommonParameters“.

INPUTS
    System.Security.AccessControl.ObjectSecurity
        You can pipe a security descriptor to Set-Acl.

OUTPUTS
    None or security object
        By default, Set-Acl does not generate any output. However, if you use the -Passthru parameter, it generates a security object. The type of the security object depends on the type of the resource.

NOTES

        The Set-Acl cmdlet is supported by the Windows PowerShell file system and Registry providers. As such, you can use it to change the security descriptors of files, directories, and Registry keys.

        When specifying multiple values for a parameter, use commas to separate the values. For example, “<parameter-name> <value1>, <value2>”.

    ————————– EXAMPLE 1 ————————–

    C:\PS>$DogACL = Get-Acl c:\dog.txt

    C:\PS>Set-Acl -Path C:\cat.txt -AclObject $DogACL

    Description
    ———–
    These commands copy the values from the security descriptor of the Dog.txt file to the security descriptor of the Cat.txt file. When the commands complete, the security descriptors of the Dog.txt and Cat.txt files are identical.

    The first command uses the Get-Acl cmdlet to get the security descriptor of the Dog.txt file. The assignment operator (=) stores the security descriptor in the value of the $DogACL Variable.

    The second command uses Set-Acl to change the values in the ACL of Cat.txt to the values in $DogACL.

    The value of the Path parameter is the path to the Cat.txt file. The value of the AclObject parameter is the model ACL, in this case, the ACL of Dog.txt as saved in the $DogACL Variable.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Get-Acl c:\dog.txt | Set-Acl -Path C:\cat.txt

    Description
    ———–
    This command is almost the same as the command in the previous example, except that it uses a pipeline operator to send the security descriptor retrieved in a Get-Acl command to a Set-Acl command.

    The first command uses the Get-Acl cmdlet to get the security descriptor of the Dog.txt file. The pipeline operator (|) passes an object that represents the Dog.txt security descriptor to the Set-Acl command.

    The second command uses Set-Acl to apply the security descriptor of Dog.txt to Cat.txt. When the command completes, the ACLs of the Dog.txt and Cat.txt files are identical.

    ————————– EXAMPLE 3 ————————–

    C:\PS>$newACL = Get-Acl file0.txt

    C:\PS>Get-ChildItem c:\temp -recurse -Include *.txt -force | Set-Acl -AclObject $newacl

    Description
    ———–
    These commands apply the security descriptors in the File0.txt file to all text files in the C:\Temp directory and all of its subdirectories.

    The first command gets the security descriptor of the File0.txt file in the current directory and uses the assignment operator (=) to store it in the $newACL Variable.

    The first command in the pipeline uses the Get-ChildItem cmdlet to get all of the text files in the C:\Temp directory. The Recurse parameter extends the command to all subdirectories of C:\temp. The Include parameter limits the files retrieved to those with the “.txt” file name extension. The Force parameter gets hidden files, which would otherwise be excluded. (You cannot use “c:\temp\*.txt”, because the Recurse parameter works on directories, not on files.)

    The pipeline operator (|) sends the objects representing the retrieved files to Set-Acl command, which applies the security descriptor in the AclObject parameter to all of the files in the pipeline.

    In practice, it is best to use the Whatif parameter with all Set-Acl commands that can affect more than one resource. In this case, the second command in the pipeline would be “Set-Acl -AclObject $newacl -WhatIf“. This command lists the files that would be affected by the command. After reviewing the result, you can run the command again without the Whatif parameter.

Alias, cmdlet, Set

Set-Alias

NAME
    Set-Alias

SYNOPSIS
    Creates or changes an Alias (alternate name) for a cmdlet or other command element in the current Windows PowerShell session.

SYNTAX
    Set-Alias [-Name] <string> [-Value] <string> [-Description <string>] [-Force] [-Option {None | ReadOnly | Constant | Private | AllScope}] [-PassThru] [-Scope <string>] [-Confirm] [-WhatIf] [<CommonParameters>]

DESCRIPTION
    The Set-Alias cmdlet creates or changes an Alias (alternate name) for a cmdlet or for a command element, such as a Function, a script, a file, or other executable. You can also use Set-Alias to reassign a current Alias to a new command, or to change any of the properties of an Alias, such as its description. Unless you add the Alias to the Windows PowerShell profile, the changes to an Alias are lost when you exit the session or close Windows PowerShell.

PARAMETERS
    -Description <string>
        Specifies a description of the Alias. You can type any string. If the description includes spaces, enclose it quotation marks.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Force [<SwitchParameter>]
        Allows the cmdlet to set a read-only Alias. Use the Option parameter to create a read-only Alias. The Force parameter cannot set a constant Alias.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Name <string>
        Specifies the new Alias. You can use any alphanumeric characters in an Alias, but the first character cannot be a number.

        Required?                    true
        Position?                    1
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -Option <ScopedItemOptions>
        Sets the value of the Options property of the Alias.

        Valid values are:

        — None: Sets no options. (default)

        — ReadOnly: The properties of the Alias cannot be changed, except by using the Force parameter. You can use Remove-Item to delete the Alias.

        — Constant: The Alias cannot be deleted and its properties cannot be changed. Constant is available only when you are creating an Alias. You cannot change the option of an existing Alias to Constant.

        — Private: The Alias is available only within the scope specified by the Scope parameter. It is invisible in all other scopes.

        — AllScope: The Alias is copied to any new scopes that are created.

        To see the Options property of the Aliases, type “Get-Alias | Format-Table -property Name, Definition, Options -autosize”.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -PassThru [<SwitchParameter>]
        Returns an object representing the Alias. By default, this cmdlet does not generate any output.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Scope <string>
        Specifies the scope in which this Alias is valid. Valid values are “Global”, “Local”, or “Script”, or a number relative to the current scope (0 through the number of scopes, where 0 is the current scope and 1 is its parent). “Local” is the default. For more information, see about_scopes.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Value <string>
        Specifies the name of the cmdlet or command element that is being Aliased.

        Required?                    true
        Position?                    2
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -Confirm [<SwitchParameter>]
        Prompts you for confirmation before executing the command.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -WhatIf [<SwitchParameter>]
        Describes what would happen if you executed the command without actually executing the command.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    <CommonParameters>
        This cmdlet supports the common parameters: Verbose, Debug,
        ErrorAction, ErrorVariable, WarningAction, WarningVariable,
        OutBuffer and OutVariable. For more information, type,
        “Get-Help about_CommonParameters“.

INPUTS
    None
        You cannot pipe input to this cmdlet.

OUTPUTS
    None or System.Management.Automation.AliasInfo
        When you use the PassThru parameter, Set-Alias generates a System.Management.Automation.AliasInfo object representing the Alias. Otherwise, this cmdlet does not generate any output.

NOTES

        An Alias is an alternate name or nickname for a cmdlet or command element. To run the cmdlet, you can use its full name or any valid Alias. For more information, see about_aliases.

        To create a new Alias, use Set-Alias or New-Alias. To delete an Alias, use Remove-Item.

        A cmdlet can have multiple Aliases, but an Alias can only be associated with one cmdlet at a time. If you use Set-Alias to associate the Alias with a different cmdlet, it is no longer associated with the original cmdlet.

        You can create an Alias for a cmdlet, but you cannot create an Alias for a command with parameters and values. For example, you can create an Alias for Set-Location, but you cannot create an Alias for “Set-Location C:\Windows\System32″. To create an Alias for a command, create a Function that includes the command, and then create an Alias to the Function.

        To save the Aliases from a session and use them in a different session, add the Set-Alias command to your Windows PowerShell profile. Profiles do not exist by default. To create a profile in the path stored in the $profile Variable, type “New-Item -type file -Force $profile”. To see the value of the $profile Variable, type “$profile”.

        You can also save your Aliases by using Export-Alias to copy the Aliases from the session to a file, and then use Import-Alias to add them to the Alias list for a new session.

        You can also refer to Set-Alias by its built-in Alias, “sal”. For more information, see about_aliases.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Set-Alias -Name list -Value Get-ChildItem

    Description
    ———–
    This command creates the Alias “list” for the Get-ChildItem cmdlet. After you create the Alias, you can use “list” in place of “Get-ChildItem” at the command line and in scripts.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Set-Alias list Get-Location

    Description
    ———–
    This command associates the Alias “list” with the Get-Location cmdlet. If “list” is an Alias for another cmdlet, this command changes its association so that it now is the Alias only for Get-Location.

    This command uses the same format as the command in the previous example, but it omits the optional parameter names, -Name and -Value. When you omit parameter names, the values of those parameters must appear in the specified order in the command. In this case, the value of -Name (“list”) must be the first parameter and the value of -Value (“Get-Location“) must be the second parameter.

    ————————– EXAMPLE 3 ————————–

    C:\PS>Set-Alias scrub Remove-Item -Option readonly -PassThru | Format-List

    Description
    ———–
    This command associates the Alias “scrub” with the Remove-Item cmdlet. It uses the “ReadOnly” option to prevent the Alias from being deleted or assigned to another cmdlet.

    The PassThru parameter directs Windows PowerShell to pass an object that represents the new Alias through the pipeline to the Format-List cmdlet. If the PassThru parameter were omitted, there would be no output from this cmdlet to display (in a list or otherwise).

    ————————– EXAMPLE 4 ————————–

    C:\PS>Set-Alias np c:\windows\notepad.exe

    Description
    ———–
    This command associates the Alias, “np”, with the executable file for Notepad. After the command completes, to open Notepad from the Windows PowerShell command line, just type “np”.

    This example demonstrates that you can create Aliases for executable files and elements other than cmdlets.

    To make the command more generic, you can use the “Windir” Environment Variable (${env:windir}) to represent the C\Windows directory. The generic version of the command is “Set-Alias np ${env:windir}\notepad.exe”.

    ————————– EXAMPLE 5 ————————–

    C:\PS>function CD32 {Set-Location c:\windows\system32}

    C:\PS>Set-Alias go cd32

    Description
    ———–
    These commands show how to assign an Alias to a command with parameters, or even to a pipeline of many commands.

    You can create an Alias for a cmdlet, but you cannot create an Alias for a command that consists of a cmdlet and its parameters. However, if you place the command in a Function or a script, then you can create a useful Function or script name and you can create one or more Aliases for the Function or script.

    In this example, the user wants to create an Alias for the command “Set-Location c:\windows\system32″, where “Set-Location” is a cmdlet and “C:\Windows\System32” is the value of the Path parameter.

    To do this, the first command creates a Function called “CD32” that contains the Set-Location command.

    The second command creates the Alias “go” for the CD32 Function. Then, to run the Set-Location command, the user can type either “CD32” or “go”.

AuthenticodeSignature, cmdlet, Set

Set-AuthenticodeSignature

NAME
    Set-AuthenticodeSignature

SYNOPSIS
    Adds an Authenticode signature to a Windows PowerShell script or other file.

SYNTAX
    Set-AuthenticodeSignature [-FilePath] <string[]> [-Certificate] <X509Certificate2> [-Force] [-HashAlgorithm <string>] [-IncludeChain <string>] [-TimestampServer <string>] [-Confirm] [-WhatIf] [<CommonParameters>]

DESCRIPTION
    The Set-AuthenticodeSignature cmdlet adds an Authenticode signature to any file that supports Subject Interface Package (SIP).

    In a Windows PowerShell script file, the signature takes the form of a block of text that indicates the end of the instructions that are executed in the script. If there is a signature in the file when this cmdlet runs, that signature is removed.

PARAMETERS
    -Certificate <X509Certificate2>
        Specifies the Certificate that will be used to sign the script or file. Enter a Variable that stores an object representing the Certificate or an expression that gets the Certificate.

        To find a Certificate, use Get-PfxCertificate or use the Get-ChildItem cmdlet in the Certificate (Cert:) drive. If the Certificate is not valid or does not have code-signing authority, the command fails.

        Required?                    true
        Position?                    2
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -FilePath <string[]>
        Specifies the path to a file that is being signed.

        Required?                    true
        Position?                    1
        Default value
        Accept pipeline input?     true (ByValue, ByPropertyName)
        Accept wildcard characters? false

    -Force [<SwitchParameter>]
        Allows the cmdlet to append a signature to a read-only file. Even using the Force parameter, the cmdlet cannot override security restrictions.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -HashAlgorithm <string>
        Specifies the hashing algorithm that Windows uses to compute the digital signature for the file. The default is SHA1, which is the Windows default hashing algorithm.

        Files that are signed with a different hashing algorithm might not be recognized on other systems.

        Required?                    false
        Position?                    named
        Default value                SHA1
        Accept pipeline input?     false
        Accept wildcard characters? false

    -IncludeChain <string>
        Determines which Certificates in the Certificate trust chain are included in the digital signature. “NotRoot” is the default.

        Valid values are:

        — Signer: Includes only the signer’s Certificate.

        — NotRoot: Includes all of the Certificates in the Certificate chain, except for the root authority.

        –All: Includes all the Certificates in the Certificate chain.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false

NOTES

    ————————– EXAMPLE 1 ————————–

    C:\PS>$cert=Get-ChildItem -Path cert:\CurrentUser\my -CodeSigningCert

    C:\PS>Set-AuthenticodeSignature -FilePath PsTestInternet2.ps1 -Certificate $cert

    Description
    ———–
    These commands retrieve a code-signing Certificate from the Windows PowerShell Certificate provider and use it to sign a Windows PowerShell script.

    The first command uses the Get-ChildItem cmdlet and the Windows PowerShell Certificate provider to get the Certificates in the Cert:\CurrentUser\My subdirectory of the Certificate store. (The Cert: drive is the drive exposed by the Certificate provider.) The CodeSigningCert parameter, which is supported only by the Certificate provider, limits the Certificates retrieved to those with code-signing authority. The command stores the result in the $cert Variable.

    The second command uses the Set-AuthenticodeSignature cmdlet to sign the PSTestInternet2.ps1 script. It uses the FilePath parameter to specify the name of the script and the Certificate parameter to specify that the Certificate is stored in the $cert Variable.

    ————————– EXAMPLE 2 ————————–

    C:\PS>$cert = Get-PfxCertificate C:\Test\Mysign.pfx

    C:\PS>Set-AuthenticodeSignature -FilePath ServerProps.ps1 -Cert $cert

    Description
    ———–
    These commands use the Get-PfxCertificate cmdlet to find a code signing Certificate. Then, they use it to sign a Windows PowerShell script.

    The first command uses the Get-PfxCertificate cmdlet to find the C:\Test\MySign.pfx Certificate and store it in the $cert Variable.

    The second command uses Set-AuthenticodeSignature to sign the script. The FilePath parameter of Set-AuthenticodeSignature specifies the path to the script file being signed and the Cert parameter passes the $cert Variable containing the Certificate to Set-AuthenticodeSignature.

    If the Certificate file is password protected, Windows PowerShell prompts you for the password.

    ————————– EXAMPLE 3 ————————–

    C:\PS>Set-AuthenticodeSignature -FilePath c:\scripts\Remodel.ps1 -Certificate $cert -IncludeChain All -TimestampServer “http://timestamp.fabrikam.com/scripts/timstamper.dll”

    Description
    ———–
    This command adds a digital signature that includes the root authority in the trust chain, and it is signed by a third-party timestamp server.

    The command uses the FilePath parameter to specify the script being signed and the Certificate parameter to specify the Certificate that is saved in the $cert Variable. It uses the IncludeChain parameter to include all of the signatures in the trust chain (including the root authority). It also uses the TimeStampServer parameter to add a timestamp to the signature. This prevents the script from failing when the Certificate expires.

cmdlet, Item, Rename

Rename-Item

NAME
    Rename-Item

SYNOPSIS
    Renames an item in a Windows PowerShell provider namespace.

SYNTAX
    Rename-Item [-Path] <string> [-NewName] <string> [-Credential <PSCredential>] [-Force] [-PassThru] [-Confirm] [-WhatIf] [-UseTransaction] [<CommonParameters>]

DESCRIPTION
    The Rename-Item cmdlet changes the name of a specified item. This cmdlet does not affect the content of the item being renamed.

    You cannot use Rename-Item to move an item, such as by specifying a path along with the new name. To move and rename an item, use the Move-Item cmdlet.

PARAMETERS
    -Credential <PSCredential>
        Specifies a user account that has permission to perform this action. The default is the current user.

        Type a user name, such as “User01” or “Domain01\User01”, or enter a PSCredential object, such as one generated by the Get-Credential cmdlet. If you type a user name, you will be prompted for a password.

        This parameter is not supported by any providers installed with Windows PowerShell.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -Force [<SwitchParameter>]
        Allows the cmdlet to rename items that cannot otherwise be changed, such as hidden or read-only files or read-only Aliases or Variables. The cmdlet cannot change constant Aliases or Variables. Implementation varies from provider to provider. For more information, see about_providers. Even using the Force parameter, the cmdlet cannot override security restrictions.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -NewName <string>
        Specifies the new name of the item. Enter only a name, not a path and name. If you enter a path that is different from the path that is specified in the Path parameter, Rename-Item generates an error. To rename and move an item, use the Move-Item cmdlet.

        You cannot use wildcard characters in the value of NewName. To specify a name for multiple files, use the Replace operator in a regular expression. For more information about the Replace operator, type “Get-Help about_Comparison_Operators“. For a demonstration, see the examples.

        Required?                    true
        Position?                    2
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -PassThru [<SwitchParameter>]
        Passes an object representing the item to the pipeline. By default, this cmdlet does not generate any output.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Path <string>
        Specifies the path to the item to rename.

        Required?                    true
        Position?                    1
        Default value
        Accept pipeline input?     true (ByValue, ByPropertyName)
        Accept wildcard characters? false

    -Confirm [<SwitchParameter>]
        Prompts you for confirmation before executing the command.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -WhatIf [<SwitchParameter>]
        Describes what would happen if you executed the command without actually executing the command.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -UseTransaction [<SwitchParameter>]
        Includes the command in the active transaction. This parameter is valid only when a transaction is in progress. For more information, see about_transactions.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    <CommonParameters>
        This cmdlet supports the common parameters: Verbose, Debug,
        ErrorAction, ErrorVariable, WarningAction, WarningVariable,
        OutBuffer and OutVariable. For more information, type,
        “Get-Help about_CommonParameters“.

INPUTS
    System.String
        You can pipe a string that contains a path to Rename-Item.

OUTPUTS
    None or an object representing the renamed item.
        When you use the Passthru parameter, Rename-Item generates an object representing the renamed item. Otherwise, this cmdlet does not generate any output.

NOTES

        The Rename-Item cmdlet is designed to work with the data exposed by any provider. To list the providers available in your session, type “Get-PSProvider“. For more information, see about_providers.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Rename-Item -Path c:\logfiles\daily_file.txt -NewName monday_file.txt

    Description
    ———–
    This command renames the file daily_file.txt to monday_file.txt.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Rename-Item -Path project.txt -NewName d:\archive\old-project.txt

    Rename-Item : Cannot rename because the target specified represents a path or device name.
    At line:1 char:12
    + Rename-Item <<<< -Path project.txt -NewName d:\archive\old-project.txt
        + CategoryInfo         : InvalidArgument: (:) [Rename-Item], PSArgumentException
        + FullyQualifiedErrorId : Argument,Microsoft.PowerShell.Commands.RenameItemCommand

    C:\PS> Move-Item -Path project.txt -destination d:\archive\old-project.txt
    # Command succeeds

    Description
    ———–
    This example shows that you cannot use the Rename-Item cmdlet to both rename and move an item. Specifically, you cannot supply a path for the value of the NewName parameter, unless the path is identical to the path specified in the Path parameter. Otherwise, only a new name is permitted.

    The first command uses the Rename-Item cmdlet to rename the project.txt file in the current directory to old-project.txt in the D:\Archive directory. The result is the error shown in the output.

    The second command shows the correct way to move and rename a file by using the Move-Item cmdlet. The Move-Item cmdlet lets you specify both a new path and a new name in the value of its Destination parameter.

    ————————– EXAMPLE 3 ————————–

    C:\PS>Rename-Item HKLM:\Software\MyCompany\Advertising -NewName Marketing

    Description
    ———–
    This command uses the Rename-Item cmdlet to rename a Registry key from Advertising to Marketing. When the command is complete, the key is renamed, but the Registry entries in the key are unchanged.

    ————————– EXAMPLE 4 ————————–

    C:\PS>Get-ChildItem *.txt | Rename-Item -NewName { $_.name -replace ‘\.txt’,’.log’ }

    Description
    ———–
    This example shows how to use the Replace operator to rename multiple files, even though the NewName parameter does not accept wildcard characters.

    This command renames all of the .txt files in the current directory to .log.

    The command uses a Get-ChildItem cmdlet to get all of the files in the current directory that have a .txt file name extension. Then, it uses the pipeline operator (|) to send the resulting files to the Rename-Item cmdlet.

    In the Rename-Item command, the value of the NewName parameter is a script block that is executed before the value is submitted to the NewName parameter.

    In the script block, the $_ automatic Variable represents each file object as it comes to the command through the pipeline. The command uses the dot format (.) to get the Name property of each file object. The Replace operator replaces the “.txt” file name extension of each file with “.log”.

    Because the Replace operator works with regular expressions, the dot preceding “txt” is interpreted to match any character. To ensure that it matches only a dot (.), it is escaped with a backslash character (\). The backslash character is not required in “.log” because it is a string, not a regular expression.

DESCRIPTION
    The Restart-Computer cmdlet restarts the operating system on the local and remote computers.

    You can use the parameters of Restart-Computer to run the restart operations as a background job, to specify the authentication levels and alternate credentials, to limit the operations that run concurrently, and to force an immediate restart.

    This cmdlet does not require Windows PowerShell remoting unless you use the AsJob parameter.

PARAMETERS

        Note: To use this parameter, the local and remote computers must be configured for remoting and, on Windows Vista and later versions of Windows, you must open Windows PowerShell with the “Run as administrator” option. For more information, see about_remote_requirements.

        When you use the AsJob parameter, the command immediately returns an object that represents the background job. You can continue to work in the session while the job completes. The job is created on the local computer and the results from remote computers are automatically returned to the local computer. To manage the job, use the Job cmdlets. To get the job results, use the Receive-Job cmdlet.

        For more information about Windows PowerShell background jobs, see about_jobs and about_remote_Jobs.

        Required?                    false

        Valid values are:

        Default:     Default impersonation.
        Anonymous:    Hides the identity of the caller.
        Identify:     Allows objects to query the credentials of the caller.
        Impersonate: Allows objects to use the credentials of the caller.

        Required?                    false
        Position?                    named
        Default value                Impersonate
        Accept pipeline input?     false
        Accept wildcard characters? false

    -ThrottleLimit <int>
        Specifies the maximum number of concurrent connections that can be established to run this command. If you omit this parameter or enter a value of 0, the default value, 32, is used.

        The throttle limit applies only to the current command, not to the session or to the computer.

    ————————– EXAMPLE 3 ————————–

    C:\PS>$j = Restart-Computer -ComputerName Server01, Server02 -AsJob

    C:\PS> $results = $j | Receive-Job

    C:\PS> $results

    Description
    ———–
    These commands run a Restart-Computer command as a background job on two remote computers, and then get the results.

    The first command uses the AsJob parameter to run the command as a background job. The command saves the resulting job object in the $j Variable.

    The second command uses a pipeline operator to send the job object in $j to the Receive-Job cmdlet, which gets the job results. The command saves the results in the $results Variable.

    The third command displays the result saved in the $results Variable.

    Because the AsJob parameter creates the job on the local computer and automatically returns the results to the local computer, you can run the Receive-Job command as a local command.

    ————————– EXAMPLE 4 ————————–

    C:\PS>Restart-Computer -comp Server01 -Impersonation anonymous -Authentication PacketIntegrity

    Description
    ———–
    This command restarts the Server01 remote computer. The command uses customized impersonation and authentication settings.

    ————————– EXAMPLE 5 ————————–

    C:\PS>$s = Get-Content domain01.txt

    C:\PS> $c = Get-Credential domain01\admin01

    C:\PS> Restart-Computer -ComputerName $s -Force -ThrottleLimit 10 -Credential $c

    Description
    ———–
    These commands force an immediate restart of all of the computers in Domain01.

    The first command gets a list of computers in the domain and saves it in the $s Variable.

    The second command gets the credentials of a domain administrator and saves them in the $c Variable.

    The third command restarts the computers. It uses the ComputerName parameter to submit the list of computers in the $s Variable, the Force parameter to force an immediate restart, and the Credential parameter to submit the credentials saved in the $c Variable. It also uses the ThrottleLimit parameter to limit the command to 10 concurrent connections.
