Description

The Set-PSSessionConfiguration cmdlet changes the properties of the session configurations on the local computer.

Use the Name parameter to identify the session 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.

Starting in PowerShell 3.0, you can use a session configuration file to define a session configuration. This feature provides a simple and discoverable method for setting and changing the properties of sessions that use the session configuration. To specify a session configuration file, use the Path parameter of Set-PSSessionConfiguration. For information about session configuration files, see about_Session_Configuration_Files. For information about how to create and modify a session configuration file, see the New-PSSessionConfigurationFile cmdlet.

Session configurations define the environment of remote sessions (PSSessions) that connect to the local computer. Every PSSession uses a session configuration. The session configuration determines the features of the PSSession, such as the modules that are available in the session, the cmdlets that are permitted to run, the language mode, quotas, and timeouts. The security descriptor of the session configuration determines who can use the session configuration to connect to the local computer. For more information about session configurations, see about_Session_Configurations.

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.

Examples

Example 1: Change the thread apartment state

PS C:\> Set-PSSessionConfiguration -Name "MaintenanceShell" -ThreadApartmentState STA

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: Create and change a session configuration

This example shows how to add and remove a startup script from a configuration.

The first command creates the AdminShell configuration. The second command adds 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.

Register-PSSessionConfiguration -Name "AdminShell" -AssemblyName "C:\Shells\AdminShell.dll" -ConfigurationTypeName "AdminClass"
Set-PSSessionConfiguration -Name "AdminShell" -StartupScript "AdminConfig.ps1"
Set-PSSessionConfiguration -Name "AdminShell" -StartupScript $Null

Example 3: Display results

This example increases the value of the MaximumReceivedObjectSizeMB property to 20. This command also prompts you to restart the WinRM service. The change is not effective until the WinRM service is restarted.

Set-PSSessionConfiguration -Name "IncObj" -MaximumReceivedObjectSizeMB 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

Example 3: Display results in different ways

In this example, Set-PSSessionConfiguration changes the startup script in the MaintenanceShell session configuration to Maintenance.ps1. The output shows the change and prompts you to restart the WinRM service. The response is y (yes).

Get-PSSessionConfiguration gets the MaintenanceShell session configuration. The pipeline operator (|) sends the results of the command to Format-List, which displays all the properties of the configuration object in a list. Next, using the WSMan provider, we view the initialization parameters for the MaintenanceShell configuration. Get-ChildItem gets the child items in the InitializationParameters node for the MaintenanceShell plug-in. For more information about the WSMan provider, type Get-Help wsman.

Parameters

-AccessMode

Enables and disables the session configuration and determines whether it can be used for remote or local sessions on the computer. The acceptable values for this parameter are:

  • Disabled. Disables the session configuration. It cannot be used for remote or local access to the computer. This value sets the Enabled property of the session configuration (WSMan:\<ComputerName>\PlugIn\<SessionConfigurationName>\Enabled) to False.
  • Local. Adds a Network_Deny_All entry to security descriptor of the session configuration. Users of the local computer can use the session configuration to create a local loopback session on the same computer, but remote users are denied access.
  • Remote. Removes Deny_All and Network_Deny_All entries from the security descriptors of the session configuration. Users of local and remote computers can use the session configuration to create sessions and run commands on this computer.

The default value is Remote.

Other cmdlets can override the value of this parameter later. For example, the Enable-PSRemoting cmdlet enables all session configurations on the computer and permits remote access to them, and the Disable-PSRemoting cmdlet permits only local access to all session configurations on the computer.

This parameter was introduced in PowerShell 3.0.

-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.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-MaximumReceivedDataSizePerCommandMB

Specifies 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.

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. The value of this parameter is ignored.

Type:Nullable<T>[Double]
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-MaximumReceivedObjectSizeMB

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

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. The value of this parameter is ignored.

Type:Nullable<T>[Double]
Position:Named
Default value:10
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-ModulesToImport

Specifies the modules and snap-ins that are automatically imported into sessions that use the session configuration. Enter the module and snap-in names.

By default, only the Microsoft.PowerShell.Core module is imported into sessions, but unless the cmdlets are excluded, you can use the Import-Module and Add-PSSnapin cmdlets to add modules and snap-ins to the session.

The modules specified in this parameter value are imported in additions to modules specified in the session configuration file (New-PSSessionConfigurationFile). However, settings in the session configuration file can hide the commands exported by modules or prevent users from using them.

The modules specified in this parameter value replace the list of modules specified with the ModulesToImport parameter of the Register-PSSessionConfiguration cmdlet.

This parameter was introduced in PowerShell 3.0.

Type:Object[]
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Name

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.

Type:String
Position:0
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-NoServiceRestart

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

By default, when you run Set-PSSessionConfiguration, 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.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Path

Specifies the path of a session configuration file (.pssc), such as one created by the New-PSSessionConfigurationFile cmdlet. If you omit the path, the default is the current directory.

This parameter was introduced in PowerShell 3.0.

Type:String
Position:Named
Default value:None
Required:True
Accept pipeline input:False
Accept wildcard characters:False

-PSVersion

Specifies the version of PowerShell in sessions that use this session configuration.

The value of this parameter takes precedence over the value of the PowerShellVersion key in the session configuration file.

This parameter was introduced in PowerShell 3.0.

Type:Version
Aliases:PowerShellVersion
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-RunAsCredential

Specifies credentials for commands in the session. By default, commands run with the permissions of the current user.

This parameter was introduced in PowerShell 3.0.

Type:PSCredential
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-SecurityDescriptorSddl

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.

Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-SessionTypeOption

Specifies type-specific options for the session configuration. Enter a session type options object, such as the PSWorkflowExecutionOption object that the New-PSWorkflowExecutionOption cmdlet returns.

The options of sessions that use the session configuration are determined by the values of session options and the session configuration options. Unless specified, options set in the session, such as with the New-PSSessionOption cmdlet, take precedence over options set in the session configuration. However, session option values cannot exceed maximum values set in the session configuration.

This parameter was introduced in PowerShell 3.0.

Type:PSSessionTypeOption
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-ShowSecurityDescriptorUI

When this parameter is used the cmdlet opens a property sheet that helps you create a new SDDL for the session configuration. The property sheet appears after you run the Set-PSSessionConfiguration command and then restart the WinRM service.

When you set 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.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-StartupScript

Specifies the startup script for the configuration. Enter the fully qualified path of a 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 session. If the script generates an error, even a non-terminating error, the session is not created and the New-PSSession command fails.

Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-ThreadApartmentState

Specifies the apartment state of the threading module to be used. Acceptable values are:

  • Unknown
  • MTA
  • STA
Type:ApartmentState
Accepted values:STA, MTA, Unknown
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-ThreadOptions

Specifies the thread options setting in the configuration. This setting defines how threads are created and used when a command is executed in the session. The acceptable values for this parameter are:

  • Default
  • ReuseThread
  • UseCurrentThread
  • UseNewThread

The default value is UseCurrentThread.

For more information, see PSThreadOptions Enumeration.

Type:PSThreadOptions
Accepted values:Default, UseNewThread, ReuseThread, UseCurrentThread
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-TransportOption

Specifies the transport options for the session configuration. Enter a transport options object, such as the WSManConfigurationOption object that the New-PSTransportOption cmdlet returns.

The options of sessions that use the session configuration are determined by the values of session options and the session configuration options. Unless specified, options set in the session, such as with the New-PSSessionOption cmdlet, take precedence over options set in the session configuration. However, session option values cannot exceed maximum values set in the session configuration.

This parameter was introduced in PowerShell 3.0.

Type:PSTransportOption
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-UseSharedProcess

Use only one process to host all sessions that are started by the same user and use the same session configuration. By default, each session is hosted in its own process.

This parameter was introduced in PowerShell 3.0.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

Type:SwitchParameter
Aliases:wi
Position:Named
Default value:False
Required:False
Accept pipeline input:False
Accept wildcard characters:False

Inputs

None

You can't pipe objects to this cmdlet.

Outputs

WSManConfigLeafElement

Notes

To run this cmdlet, start PowerShell by using 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 session 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.

The properties of a session configuration object vary with the options set for the session configuration and the values of those options. Also, session configurations that use a session configuration file have additional properties.

You can use commands in the WSMan: drive to change the properties of session configurations. However, you cannot use the WSMan: drive in PowerShell 2.0 to change session configuration properties that are introduced in PowerShell 3.0, such as OutputBufferingMode. Windows PowerShell 2.0 commands do not generate an error, but they are ineffective. To change properties introduced in PowerShell 3.0, use the WSMan: drive in PowerShell 3.0 or later.
