说明
The Update-DscConfiguration cmdlet connects to a pull server, downloads the configuration if it
differs from what is current on the node, and then applies the configuration to the computer.
This cmdlet is available only as part of the November 2014 update rollup for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2.
示例
Example 1: Update a configuration
Update-DscConfiguration -Wait -Verbose
After running this command, the server will connect to the registered pull service, download the latest assigned configuration, and then apply it. The Wait and Verbose parameters are optional. When working interactively, these parameters combined enable real-time feedback about progress and success or failure when applying the configuration.
Example 2: Update a configuration by connecting over a CIM session
$Session = New-CimSession -ComputerName "Server01" -Credential ACCOUNTS\PattiFuller
Update-DscConfiguration -CimSession $Session -Wait
The first command creates a CIM session by using the New-CimSession cmdlet, and then stores the
CimSession object in the $Session variable. The command prompts you for a password. For more
information, type Get-Help New-CimSession.
The second command updates the computer specified in the CimSession stored in $Session. The
command specifies the Wait parameter. The console does not accept additional commands until the
current command finishes.
参数
-CimSession
Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

-JobName
Specifies a friendly name for a job. If you specify this parameter, the cmdlet runs as a job, and it returns a Job object.
By default, Windows PowerShell assigns the name JobN where N is an integer.
If you specify the Wait parameter, do not specify this parameter.

-ThrottleLimit
Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If
this parameter is omitted or a value of 0 is entered, then Windows PowerShell calculates an
optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the
computer. The throttle limit applies only to the current cmdlet, not to the session or to the
computer.
