Set-PSSessionConfiguration

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

-ApplicationBase <string>

Changes the path to the assembly file (*.dll) that is specified in the value of the AssemblyName parameter.

-AssemblyName <string>

Specifies a different assembly file for the configuration. Enter the path (optional) and file name of an assembly (.dll) file that defines the configuration type.

If you enter only the name, you can enter the path in the value of the ApplicationBase parameter.

-ConfigurationTypeName <string>

Specifies a different configuration type for the configuration. The type that you specify must implement the System.Management.Automation.Remoting.PSSessionConfiguration class.

If you enter "$null" or an empty string, the DefaultRemotePowerShellConfiguration class is used for the session configuration.

-Force

Suppresses all user prompts, and restarts the WinRM service without prompting. Restarting the service makes the configuration change effective.

To prevent a restart and suppress the restart prompt, use the NoServiceRestart parameter.

-MaximumReceivedDataSizePerCommandMB <double>

Changes the limit on the amount of data that can be sent to this computer in any single remote command. Enter the data size in megabytes (MB). The default is 50 MB.

If a data size limit is defined in the configuration type that is specified in the ConfigurationTypeName parameter, the limit in the configuration type is used and the value of this parameter is ignored.

-MaximumReceivedObjectSizeMB <double>

Changes the limits on the amount of data that can be sent to this computer in any single object. Enter the data size in megabytes (MB). The default is 10 MB.

If an object size limit is defined in the configuration type that is specified in the ConfigurationTypeName parameter, the limit in the configuration type is used and the value of this parameter is ignored.

-Name <string>

Specifies the name of the session configuration that you want to change.

You cannot use this parameter to change the name of the session configuration.

-NoServiceRestart

Does not restart the WinRM service, and suppresses the prompt to restart the service.

By default, when you enter a Set-PSSessionConfiguration command, you are prompted to restart the WinRM service to make the new session configuration effective. Until the WinRM service is restarted, the new session configuration is not effective.

To restart the WinRM service without prompting, use the Force parameter. To restart the WinRM service manually, use the Restart-Service cmdlet.

-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.

-ShowSecurityDescriptorUI

Displays a property sheet that helps you to create a new SDDL for the session configuration. The property sheet appears after you enter the Set-PSSessionConfiguration command and then restart the WinRM service.

When setting the permissions to the configuration, remember that users must have at least "Execute(Invoke)" permission to use the session configuration in a session.

You cannot use the SecurityDescriptorSDDL parameter and this parameter in the same command.

-StartupScript <string>

Adds or changes the startup script for the configuration. Enter the fully qualified path to a Windows PowerShell script. The specified script runs in the new session that uses the session configuration.

To delete a startup script from a session configuration, enter an empty string ("") or a value of $null.

You can use a startup script to further configure the user's session. If the script generates an error (even a non-terminating error), the session is not created and the user's New-PSSession command fails.

-ThreadApartmentState <ApartmentState>

Changes the apartment state setting for the threads in the session. Valid values are STA, MTA and Unknown. Unknown is the default.

-ThreadOptions <PSThreadOptions>

Changes the thread options setting in the configuration. This setting defines how threads are created and used when a command is executed in the session. Valid values are Default, ReuseThread, UseCurrentThread, and UseNewThread. UseCurrentThread is the default.

-Confirm

Prompts you for confirmation before executing the command.

-WhatIf

Describes what would happen if you executed the command without actually executing the command.

<CommonParameters>

This command supports the common parameters: Verbose, Debug, ErrorAction, ErrorVariable, OutBuffer, OutVariable, WarningAction, and WarningVariable. For more information, see about_CommonParameters.

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.

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

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".
