Get-PSSessionConfiguration

  • Reference
Module:
Microsoft.PowerShell.Core

Gets the registered session configurations on the computer.

Syntax

Get-PSSessionConfiguration
   [[-Name] <String[]>]
   [-Force]
   [<CommonParameters>]

Description

The Get-PSSessionConfiguration cmdlet gets the session configurations that have been registered 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.

Beginning in PowerShell 3.0, you can define the properties of a session configuration by using a session configuration (.pssc) file. This feature lets you create customized and restricted sessions without writing a computer program. For more information about session configuration files, see about_Session_Configuration_Files.

Also, beginning in PowerShell 3.0, new note properties have been added to the session configuration object that Get-PSSessionConfiguration returns. These properties make it easier for users and session configuration authors to examine and compare session configurations.

To create and register a session configuration, use the Register-PSSessionConfiguration cmdlet. For more information about session configurations, see about_Session_Configurations.

Examples

Example 1 - Get session configurations on the local computer

Get-PSSessionConfiguration

Example 2 - Get the two default session configurations

The command uses the Name parameter of Get-PSSessionConfiguration to get only the session configurations with names that begin with "Microsoft".

Get-PSSessionConfiguration -Name Microsoft*

Name                      PSVersion  StartupScript        Permission
----                      ---------  -------------        ----------
microsoft.powershell      5.1                             BUILTIN\Administrators AccessAll...
microsoft.powershell32    5.1                             BUILTIN\Administrators AccessAll...

Example 3 - Get the properties and values of a session configuration

This example shows the properties and property values of a session configuration that was created by using a session configuration file.

Get-PSSessionConfiguration -Name Full  | Format-List -Property *

The example uses the Get-PSSessionConfiguration cmdlet to get the full session configuration. A pipeline operator sends the Full session configuration to the Format-List cmdlet. The Property parameter with a value of * (all) directs Format-List to display all the properties and values of the object in a list.

The output includes useful information, including the author of the session configuration, the session type, language mode, and execution policy of sessions that are created with this session configuration, session quotas, and the full path to the session configuration file.

This view of a session configuration is used for sessions that include a session configuration file. For more information about session configuration files, see about_Session_Configuration_Files.

Example 4 - Another way to look at the session configurations

This example uses the Get-ChildItem cmdlet (alias dir) in the WSMan: provider drive to look at the content of the Plugin node. This is another way to look at the session configurations on the computer.

dir wsman:\localhost\plugin

Type            Keys                                Name
----            ----                                ----
Container       {Name=Event Forwarding Plugin}      Event Forwarding Plugin
Container       {Name=Full}                         Full
Container       {Name=microsoft.powershell}         microsoft.powershell
Container       {Name=microsoft.powershell.workf... microsoft.powershell.workflow
Container       {Name=microsoft.powershell32}       microsoft.powershell32
Container       {Name=microsoft.ServerManager}      microsoft.ServerManager
Container       {Name=WMI Provider}                 WMI Provider

The PlugIn node contains ContainerElement objects (Microsoft.WSMan.Management.WSManConfigContainerElement) that represent the registered PowerShell session configurations, along with other plug-ins for WS-Management.

Example 6 - View session configurations on a remote computer

This example shows how to use the WSMan provider to view the session configurations on a remote computer. This method does not provide as much information as a Get-PSSessionConfiguration command, but the user does not need to be a member of the Administrators group to run this cmdlet.

Connect-WSMan -ComputerName Server01
dir WSMan:\Server01\Plugin

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

Type            Keys                                Name
----            ----                                ----
Container       {Name=Empty}                        Empty
Container       {Name=Event Forwarding Plugin}      Event Forwarding Plugin
Container       {Name=Full}                         Full
Container       {Name=microsoft.powershell}         microsoft.powershell
Container       {Name=microsoft.powershell.workf... microsoft.powershell.workflow
Container       {Name=microsoft.powershell32}       microsoft.powershell32
Container       {Name=microsoft.ServerManager}      microsoft.ServerManager
Container       {Name=NoLanguage}                   NoLanguage
Container       {Name=RestrictedLang}               RestrictedLang
Container       {Name=RRS}                          RRS
Container       {Name=SEL Plugin}                   SEL Plugin
Container       {Name=WithProfile}                  WithProfile
Container       {Name=WMI Provider}                 WMI Provider

The Connect-WSMan cmdlet connects to the WinRM service on the Server01 remote computer. The Get-ChildItem cmdlet (alias dir) of the WSMan: drive gets the items in the Server01\Plugin path. The output shows the items in the Plugin directory on the Server01 computer. The items include the session configurations, which are a type of WSMan plug-in, along with other types of plug-ins on the computer.

Example 7 - Get detailed session configurations from a remote computer

This example shows how to run a Get-PSSessionConfiguration command on a remote computer. The command requires that CredSSP delegation be enabled in the client settings on the local computer and in the service settings on the remote computer.

To run the commands in this example, you must be a member of the Administrators group on the local and remote computers and you must start PowerShell with the Run as administrator option.

Enable-WSManCredSSP -Delegate Server02
Connect-WSMan Server02
Set-Item WSMan:\Server02*\Service\Auth\CredSSP -Value $true
Invoke-Command -ScriptBlock {Get-PSSessionConfiguration} -ComputerName Server02 -Authentication CredSSP -Credential Domain01\Admin01

Name                      PSVersion  StartupScript        Permission                          PSComputerName
----                      ---------  -------------        ----------                          --------------
microsoft.powershell      5.1                             BUILTIN\Administrators AccessAll... server02.corp.fabrikam.com
microsoft.powershell32    5.1                             BUILTIN\Administrators AccessAll... server02.corp.fabrikam.com
MyX86Shell                5.1        c:\test\x86Shell.ps1 BUILTIN\Administrators AccessAll... server02.corp.fabrikam.com

The Enable-WSManCredSSP cmdlet enables CredSSP delegation on Server01, the local computer. The Connect-WSMan cmdlet connects to Server02 computer. This action adds a node for Server02 to the WSMan: drive on the local computer, allowing you to view and change the WS-Management settings on the Server02 computer. The Set-Item cmdlet changes the value of the CredSSP item in the Service node of the Server02 computer to True. This configures the service settings on the remote computer. The Invoke-Command cmdlet runs theGet-PSSessionConfiguration command on the Server02 computer. The command uses the Credential parameter, and it uses the Authentication parameter with a value of CredSSP. The output shows the session configurations on the Server02 remote computer.

Example 8 - Get the resource URI of a session configuration

This example is useful for setting the value of the $PSSessionConfigurationName preference variable, which takes a resource URI.

(Get-PSSessionConfiguration -Name CustomShell).resourceURI

http://schemas.microsoft.com/powershell/microsoft.CustomShell

The $PSSessionConfigurationName variable specifies the default configuration that is used when you create a session. This variable is set on the local computer, but it specifies a configuration on the remote computer. For more information about the $PSSessionConfiguration variable, see about_Preference_Variables.

Notes

  • To run this cmdlet, start PowerShell with the Run as administrator option.

  • To view the session configurations on the computer, you must be a member of the Administrators group on the computer.

  • To run a Get-PSSessionConfiguration command on a remote computer, Credential Security Service Provider (CredSSP) authentication must be enabled in the client settings on the local computer (by using the Enable-WSManCredSSP cmdlet) and in the service settings on the remote computer. Also, you must use the CredSSP value of the Authentication parameter when establishing the remote session. Otherwise, access is denied.

  • The note properties of the object that Get-PSSessionConfiguration returns appear on the object only when they have a value. Only session configurations that were created by using a session configuration file have all the defined properties.

  • 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. 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.
