Description

This cmdlet is only available on the Windows platform.

The Register-PSSessionConfiguration cmdlet creates and registers a new session configuration on the local computer. This is an advanced cmdlet that you can use to create custom sessions for remote users.

Every PowerShell session (PSSession) uses a session configuration, also known as an endpoint. When users create a session that connects to the computer, they can select a session configuration or use the default session configuration that is registered when you enable PowerShell remoting. Users can also set the $PSSessionConfigurationName preference variable, which specifies a default configuration for remote sessions created in the current session.

The session configuration defines the environment for the remote session. The configuration can determine which commands and language elements are available in the session, and it can include settings that protect the computer, such as those that limit the amount of data that the session can receive remotely in a single object or command. The security descriptor of the session configuration determines which users have permission to use the session configuration.

You can define the elements of configuration by using an assembly that implements a new configuration class and by using a script that runs in the session. Beginning in PowerShell 3.0, you can also use a session configuration file to define the session configuration.

For information about session configurations, see about_Session_Configurations. For information about session configuration files, see about_Session_Configuration_Files.

Examples

Example 1: Register a NewShell session configuration

In this example, we register the NewShell session configuration. The AssemblyName and ApplicationBase parameters specify the location of the MyShell.dll file, which specifies the cmdlets and providers in the session configuration. The ConfigurationTypeName parameter specifies the configuration class to use from the assembly.

$sessionConfiguration = @{
    Name='NewShell'
    ApplicationBase='c:\MyShells\'
    AssemblyName='MyShell.dll'
    ConfigurationTypeName='MyClass'
}
Register-PSSessionConfiguration @sessionConfiguration

To use this configuration, type New-PSSession -ConfigurationName newshell.

Example 2: Register a MaintenanceShell session configuration

This example registers the MaintenanceShell session configuration on the local computer. The StartupScript parameter specifies the Maintenance.ps1 script.

Register-PSSessionConfiguration -Name MaintenanceShell -StartupScript C:\ps-test\Maintenance.ps1

When a user uses a New-PSSession command and selects the MaintenanceShell configuration, the Maintenance.ps1 script runs in the new session. The script can configure the session. This includes importing modules and setting the execution policy for the session. If the script generates any errors, including non-terminating errors, the New-PSSession command fails.

Example 3: Register a session configuration

This example registers the AdminShell session configuration.

The $sessionParams variable is a hashtable containing all the parameter values. This hashtable is passed to the cmdlet using PowerShell splatting. The Register-PSSessionConfiguration command uses the SecurityDescritorSDDL parameter to specify the SDDL in the value of the $sddl variable and the MaximumReceivedObjectSizeMB parameter to increase the object size limit. It also uses the StartupScript parameter to specify a script that configures the session.

$sddl = "O:NSG:BAD:P(A;;GA;;;BA)S:P(AU;FA;GA;;;WD)(AU;FASA;GWGX;;;WD)"
$sessionParams = @{
    Name="AdminShell"
    SecurityDescriptorSDDL=$sddl
    MaximumReceivedObjectSizeMB=20
    StartupScript="C:\scripts\AdminShell.ps1"
}
Register-PSSessionConfiguration @sessionParams

Example 4: Return a configuration container element

This example shows how to register the MaintenanceShell configuration. Register-PSSessionConfiguration returns a WSManConfigContainerElement object stored in the $s variable. Format-List displays all the properties of the returned object. The PSPath property shows that the object is stored in a directory of the WSMan: drive. Get-ChildItem (alias dir) displays the items in the WSMan:\LocalHost\PlugIn path. These include the new MaintenanceShell configuration and the two default configurations that come with PowerShell.

$s = Register-PSSessionConfiguration -Name MaintenanceShell -StartupScript C:\ps-test\Maintenance.ps1
$s | Format-List -Property *
dir WSMan:\LocalHost\Plugin

PSPath            : Microsoft.WSMan.Management\WSMan::localhost\Plugin\MaintenanceShell
PSParentPath      : Microsoft.WSMan.Management\WSMan::localhost\Plugin
PSChildName       : MaintenanceShell
PSDrive           : WSMan
PSProvider        : Microsoft.WSMan.Management\WSMan
PSIsContainer     : True
Keys              : {Name=MaintenanceShell}
Name              : MaintenanceShell
TypeNameOfElement : Container

Name                      Type                 Keys
----                      ----                 ----
MaintenanceShell          Container            {Name=MaintenanceShell}
microsoft.powershell      Container            {Name=microsoft.powershell}
microsoft.powershell32    Container            {Name=microsoft.powershell32}

Example 5: Register a session configuration with a startup script

In this example we create and register the WithProfile session configuration. The StartupScript parameter directs PowerShell to run the specified script for any session that uses the session configuration.

Register-PSSessionConfiguration -Name WithProfile -StartupScript Add-Profile.ps1

The script contains a single command that uses dot sourcing to run the user's CurrentUserAllHosts profile in the current scope of the session.

For more information about profiles, see about_Profiles. For more information about dot sourcing, see about_Scopes.

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.
Local. Allows users of the local computer to use the session configuration to create a local loopback session on the same computer, but denies access to remote users.
Remote. Allows local and remote users to 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 allows for remote access to all session configurations, the Enable-PSSessionConfiguration cmdlet enables session configurations, and the Disable-PSRemoting cmdlet prevents remote access to all session configurations.

This parameter was introduced in PowerShell 3.0.

Type:	PSSessionConfigurationAccessMode
Accepted values:	Disabled, Local, Remote
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-ApplicationBase

Specifies the path of the assembly file (*.dll) that is specified in the value of the AssemblyName parameter. Use this parameter when the value of the AssemblyName parameter does not include a path. The default is the current directory.

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

-AssemblyName

Specifies the name of an assembly file (*.dll) in which the configuration type is defined. You can specify the path of the .dll in this parameter or in the value of the ApplicationBase parameter.

This parameter is required when you specify the ConfigurationTypeName parameter.

Type:	String
Position:	1
Default value:	None
Required:	True
Accept pipeline input:	False
Accept wildcard characters:	False

-ConfigurationTypeName

Specifies the fully qualified name of the Microsoft .NET Framework type that is used for this configuration. The type that you specify must implement the System.Management.Automation.Remoting.PSSessionConfiguration class.

To specify the assembly file (*.dll) that implements the configuration type, specify the AssemblyName and ApplicationBase parameters.

Creating a type lets you control more aspects of the session configuration, such as exposing or hiding certain parameters of cmdlets, or setting data size and object size limits that users cannot override.

If you omit this parameter, the DefaultRemotePowerShellConfiguration class is used for the session configuration.

Type:	String
Position:	2
Default value:	None
Required:	True
Accept pipeline input:	False
Accept wildcard characters:	False

-Confirm

Prompts you for confirmation before running the cmdlet.

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

-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, specify the NoServiceRestart parameter.

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

-MaximumReceivedDataSizePerCommandMB

Specifies a limit for 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.

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

-MaximumReceivedObjectSizeMB

Specifies a limit for 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 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.

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

-ModulesToImport

Specifies the modules that are automatically imported into sessions that use the session configuration.

By default, only Microsoft.PowerShell.Core is imported into sessions. Unless the cmdlets are excluded, you can use Import-Module to add modules to the session.

The modules specified in this parameter value are imported in additions to modules that are specified by the SessionType parameter and those listed in the ModulesToImport key 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.

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 a name for the session configuration. This parameter is required.

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 a Register-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, specify 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 and filename of a session configuration file (.pssc), such as one created by New-PSSessionConfigurationFile. 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

-ProcessorArchitecture

Determines whether a 32-bit or 64-bit version of the PowerShell process is started in sessions that use this session configuration. The acceptable values for this parameter are: x86 (32-bit) and AMD64 (64-bit). The default value is determined by the processor architecture of the computer that hosts the session configuration.

You can use this parameter to create a 32-bit session on a 64-bit computer. Attempts to create a 64-bit process on a 32-bit computer fail.

Type:	String
Aliases:	PA
Accepted values:	x86, amd64
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-PSVersion

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

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 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.

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

If you omit this parameter, the root SDDL for the WinRM service is used for this configuration. To view or change the root SDDL, use the WSMan provider. For example Get-Item wsman:\localhost\service\rootSDDL. For more information about the WSMan provider, type Get-Help wsman.

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 by using 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

Indicates that this cmdlet displays a property sheet that helps you create the SDDL for the session configuration. The property sheet appears after you enter the Register-PSSessionConfiguration command and then restart the WinRM service.

When setting the permissions for 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 fully qualified path of a PowerShell script. The specified script runs in the new session that uses the session configuration.

You can use the script to additionally configure the 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
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-ThreadOptions

Specifies how threads are created and used when a command runs 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

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

WSManConfigContainerElement

Notes

This cmdlet is only available on Windows platforms.

To run this cmdlet you must start PowerShell by using the Run as administrator option.

This cmdlet generates XML that represents a Web Services for Management (WS-Management) plug-in configuration and sends the XML to WS-Management, which registers the plug-in on the local computer (New-Item wsman:\localhost\plugin).

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.
