Set-PSSessionConfiguration

Updated: April 21, 2010

Applies To: Windows PowerShell 2.0

Changes the properties of a registered session configuration.

Syntax

Set-PSSessionConfiguration [-Name] <string> [-AssemblyName] <string> [-ConfigurationTypeName] <string> [-ApplicationBase <string>] [-Force] [-MaximumReceivedDataSizePerCommandMB <double>] [-MaximumReceivedObjectSizeMB <double>] [-NoServiceRestart] [-SecurityDescriptorSDDL <string>] [-ShowSecurityDescriptorUI] [-StartupScript <string>] [-ThreadApartmentState {<STA> | <MTA> | <Unknown>}] [-ThreadOptions {<Default> | <UseNewThread> | <ReuseThread> | <UseCurrentThread>}] [-Confirm] [-WhatIf] [<CommonParameters>]

Description

The Set-PSSessionConfiguration cmdlet changes the properties of the registered session configurations on the local computer. This is an advanced cmdlet that is designed to be used by system administrators to manage customized session configurations for their users.

Use the Name parameter to identify the configuration that you want to change. Use the other parameters to specify new values for the properties of the session configuration. To delete a property value from the configuration (and use the default value), enter an empty string ("") or a value of $null for the corresponding parameter.

To see the properties of a session configuration, use the Get-PSSessionConfiguration cmdlet or the WSMan Provider. For more information about the WSMan Provider, type "Get-Help wsman".

Parameters

-SecurityDescriptorSDDL <string>

Specifies a different Security Descriptor Definition Language (SDDL) string for the configuration.

This string determines the permissions that are required to use the new session configuration. To use a session configuration in a session, users must have at least "Execute(Invoke)" permission for the configuration.

To use the default security descriptor for the configuration, enter an empty string ("") or a value of $null. The default is the root SDDL in the WSMan: drive.

If the security descriptor is complex, consider using the ShowSecurityDescriptorUI parameter instead of this one. You cannot use both parameters in the same command.

 

Required?

false

Inputs and Outputs

The input type is the type of the objects that you can pipe to the cmdlet. The return type is the type of the objects that the cmdlet returns.

 

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 WSMan 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 IncObj -MaximumReceivedObjectSizeMB 20

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

ParamName                       ParamValue
---------                       ----------
psmaximumreceivedobjectsizemb   20

"Restart WinRM service"
WinRM service need to be restarted to make the changes effective. Do you want to run the command "restart-service winrm"?
[Y] Yes  [N] No  [S] Suspend  [?] Help (default is "Y"): y

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.







Example 4

C:\PS>set-pssessionconfiguration -name MaintenanceShell -startupScript c:\ps-test\Maintenance.ps1


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

ParamName            ParamValue
---------            ----------
startupscript        c:\ps-test\Mainte...

"Restart WinRM service"
WinRM service need to be restarted to make the changes effective. Do you want to run the command "restart-service winrm"?
[Y] Yes  [N] No  [S] Suspend  [?] Help (default is "Y"): y


C:\PS> get-pssessionConfiguration maintenanceshell | format-list -property *

---------     ----------
PSVersion     2.0
startupscript c:\ps-test\Maintenance.ps1

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 WSMan 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 WSMan provider, type "get-help wsman".
