Get-Service

NAME
    Get-Service

SYNOPSIS
    Gets the services on a local or remote computer.

SYNTAX
    Get-Service [[-Name] <string[]>] [-ComputerName <string[]>] [-DependentServices] [-Exclude <string[]>] [-Include <string[]>] [-RequiredServices] [<CommonParameters>]

    Get-Service -DisplayName <string[]> [-ComputerName <string[]>] [-DependentServices] [-Exclude <string[]>] [-Include <string[]>] [-RequiredServices] [<CommonParameters>]

    Get-Service [-InputObject <ServiceController[]>] [-ComputerName <string[]>] [-DependentServices] [-Exclude <string[]>] [-Include <string[]>] [-RequiredServices] [<CommonParameters>]

DESCRIPTION
    The Get-Service cmdlet gets objects that represent the services on a local computer or on a remote computer, including running and stopped services.

    You can direct Get-Service to get only particular services by specifying the service name or display name of the services, or you can pipe service objects to Get-Service.

PARAMETERS
    -ComputerName <string[]>
        Gets the services running on the specified computers. The default is the local computer.

        Type the NetBIOS name, an IP address, or a fully qualified domain name of a remote computer. To specify the local computer, type the computer name, a dot (.), or “localhost”.

        This parameter does not rely on Windows PowerShell remoting. You can use the ComputerName parameter of Get-Service even if your computer is not configured to run remote commands.

    <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.ServiceProcess.ServiceController, System.String
        You can pipe a service object or a service name to Get-Service.

OUTPUTS
    System.ServiceProcess.ServiceController
        Get-Service returns objects that represent the services on the computer.

NOTES

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

        Get-Service can display services only when the current user has permission to see them. If Get-Service does not display services, you might not have permission to see them.

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

        When you sort in ascending order by status value, “Stopped” services appear before “Running” services. The Status property of a service is an enumerated value in which the names of the statuses represent integer values. The sort is based on the integer value, not the name. “Running” appears before “Stopped” because “Stopped” has a value of “1”, and “Running” has a value of “4”.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Get-Service

    Description
    ———–
    This command retrieves all of the services on the system. It behaves as though you typed “Get-Service *”. The default display shows the status, service name, and display name of each service.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Get-Service wmi*

    Description
    ———–
    This command retrieves services with service names that begin with “WMI” (the acronym for Windows Management Instrumentation).

    ————————– EXAMPLE 3 ————————–

    C:\PS>Get-Service -displayname *network*

    Description
    ———–
    This command displays services with a display name that includes the word
    “network”. Searching the display name finds network-related services even when the service name does not include “Net”, such as xmlprov, the Network Provisioning Service.

    ————————– EXAMPLE 4 ————————–

    C:\PS>Get-Service -Name win* -Exclude winrm

    Description
    ———–
    These commands get only the services with service names that begin with “win”, except for the WinRM service.

    ————————– EXAMPLE 5 ————————–

    C:\PS>Get-Service | Where-Object {$_.Status -eq “Running”}

    Description
    ———–
    This command displays only the services that are currently running. It uses the Get-Service cmdlet to get all of the services on the computer. The pipeline operator (|) passes the results to the Where-Object cmdlet, which selects only the services with a Status property that equals “Running”.

    Status is only one property of service objects. To see all of the properties, type “Get-Service | Get-Member“.

    ————————– EXAMPLE 6 ————————–

    C:\PS>Get-Service -ComputerName Server02

    Description
    ———–
    This command gets the services on the Server02 remote computer.

    Because the ComputerName parameter of Get-Service does not use Windows PowerShell remoting, you can use this parameter even if the computer is not configured for remoting in Windows PowerShell.

    ————————– EXAMPLE 7 ————————–

    C:\PS>Get-Service | Where-Object {$_.DependentServices} | Format-List -property Name, DependentServices, @{Label=”NoOfDependentS
    ervices”; Expression={$_.dependentservices.count}}

    Name                 : AudioEndpointBuilder
    DependentServices     : {AudioSrv}
    NoOfDependentServices : 1

    Name                 : Dhcp
    DependentServices     : {WinHttpAutoProxySvc}
    NoOfDependentServices : 1
    …

    Description
    ———–
    These commands list the services on the computer that have dependent services.

    The first command uses the Get-Service cmdlet to get the services on the computer. A pipeline operator (|) sends the services to the Where-Object cmdlet, which selects the services whose DependentServices property is not null.

    Another pipeline operator sends the results to the Format-List cmdlet. The command uses its Property parameter to display the name of the service, the name of the dependent services, and a calculated property that displays the number of dependent services that each service has.

    ————————– EXAMPLE 8 ————————–

    C:\PS>C:\PS> Get-Service s* | Sort-Object status

    Status Name             DisplayName
    —— —-             ———–
    Stopped stisvc             Windows Image Acquisition (WIA)
    Stopped SwPrv             MS Software Shadow Copy Provider
    Stopped SysmonLog         Performance Logs and Alerts
    Running Spooler            Print Spooler
    Running srservice         System Restore Service
    Running SSDPSRV            SSDP Discovery Service
    Running ShellHWDetection Shell Hardware Detection
    Running Schedule         Task Scheduler
    Running SCardSvr         Smart Card
    Running SamSs             Security Accounts Manager
    Running SharedAccess     Windows Firewall/Internet Connectio…
    Running SENS             System Event Notification
    Running seclogon         Secondary Logon

    C:\PS> Get-Service s* | Sort-Object status -descending

    Status Name             DisplayName
    —— —-             ———–
    Running ShellHWDetection Shell Hardware Detection
    Running SharedAccess     Windows Firewall/Internet Connectio…
    Running Spooler            Print Spooler
    Running SSDPSRV            SSDP Discovery Service
    Running srservice         System Restore Service
    Running SCardSvr         Smart Card
    Running SamSs             Security Accounts Manager
    Running Schedule         Task Scheduler
    Running SENS             System Event Notification
    Running seclogon         Secondary Logon
    Stopped SysmonLog         Performance Logs and Alerts
    Stopped SwPrv             MS Software Shadow Copy Provider
    Stopped stisvc             Windows Image Acquisition (WIA)

    Description
    ———–
    This command shows that when you sort services in ascending order by the value of their Status property, stopped services appear before running services. This happens because the value of Status is an enumeration, in which “Stopped” has a value of “1”, and “Running” has a value of 4.

    To list running services first, use the Descending parameter of the Sort-Object cmdlet.

    ————————– EXAMPLE 9 ————————–

    C:\PS>Get-Service -Name winrm -ComputerName localhost, Server01, Server02 | Format-Table -property MachineName, Status, Name, DisplayName -auto

    MachineName    Status Name DisplayName
    ———— —— —- ———–
    localhost     Running WinRM Windows Remote Management (WS-Management)
    Server01     Running WinRM Windows Remote Management (WS-Management)
    Server02     Running WinRM Windows Remote Management (WS-Management)

    Description
    ———–
    This command uses the Get-Service cmdlet to run a “Get-Service Winrm” command on two remote computers and the local computer (“localhost”).

    The Get-Service command runs on the remote computers, and the results are returned to the local computer. A pipeline operator (|) sends the results to the Format-Table cmdlet, which formats the services as a table. The Format-Table command uses the Property parameter to specify the properties displayed in the table, including the MachineName property.

    ————————– EXAMPLE 10 ————————–

    C:\PS>Get-Service winrm -RequiredServices

    Description
    ———–
    This command gets the services that the WinRM service requires.

    The command returns the value of the ServicesDependedOn property of the service.

    ————————– EXAMPLE 11 ————————–

    C:\PS>”winrm” | Get-Service

    Description
    ———–
    This command gets the WinRM service on the local computer. This example shows that you can pipe a service name string (enclosed in quotation marks) to Get-Service.
