DESCRIPTION
    The Invoke-WmiMethod cmdlet calls WMI methods.

PARAMETERS
    -ArgumentList <Object[]>
        Specifies the parameters to pass to the called method. The value of this parameter must be an array of objects and they must appear in the order required by the called method.

        Important: A second value of $null is required, otherwise the command will generate an error, such as “Unable to cast object of type ‘System.Byte’ to type ‘System.Array’.”.

        An example using an array of objects ($binSD) followed by a null value ($null) follows:

        PS C:\> $acl = Get-Acl test.txt
        PS C:\> $binSD = $acl.GetSecurityDescriptorBinaryForm()
        PS C:\> Invoke-WmiMethod -Class Win32_SecurityDescriptorHelper -Name BinarySDToSDDL -ArgumentList $binSD, $null

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

    -AsJob [<SwitchParameter>]
        Runs the command as a background job. Use this parameter to run commands that take a long time to finish.

        When you use the AsJob parameter, the command returns an object that represents the background job and then displays the command prompt. You can continue to work in the session while the job finishes. If Invoke-WmiMethod is used against a remote computer, 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 cmdlets that contain the Job noun (the Job cmdlets). To get the job results, use the Receive-Job cmdlet.

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

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

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

    -Authentication <AuthenticationLevel>
        Specifies the authentication level to be used with the WMI connection. Valid values are:

        -1: Unchanged
        0: Default
        1: None (No authentication in performed.)
        2: Connect (Authentication is performed only when the client establishes a relationship with the application.)
        3: Call (Authentication is performed only at the beginning of each call when the application receives the request.)
        4: Packet (Authentication is performed on all the data that is received from the client.)
        5: PacketIntegrity (All the data that is transferred between the client and the application is authenticated and verified.)
        6: PacketPrivacy (The properties of the other authentication levels are used, and all the data is encrypted.)

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

    -Authority <string>
        Specifies the authority to use to authenticate the WMI connection. You can specify standard NTLM or Kerberos authentication. To use NTLM, set the authority setting to ntlmdomain:<DomainName>, where <DomainName> identifies a valid NTLM domain name. To use Kerberos, specify kerberos:<DomainName\ServerName>. You cannot include the authority setting when you connect to the local computer.

        Required?                    false

Use the local computer name, use localhost, or use a dot (.) to specify the local computer. The local computer is the default. When the remote computer is in a different domain from the user, a fully qualified domain name is required. You can also set the value of this parameter by piping the value to the parameter.
