Remove-PSSnapin

Applies To: Windows PowerShell 2.0

Removes Windows PowerShell snap-ins from the current session.

Syntax

Remove-PSSnapin [-Name] <string[]> [-PassThru] [-Confirm] [-WhatIf] [<CommonParameters>]

Description

The Remove-PSSnapin cmdlet removes a Windows PowerShell snap-in from the current session. You can use it to remove snap-ins that you have added to Windows PowerShell, but you cannot use it to remove the snap-ins that are installed with Windows PowerShell.

After a snap-in is removed from the current session, it is still loaded, but the cmdlets and providers in the snap-in are no longer available in the session.

Specifies the names of Windows PowerShell snap-ins to remove from the current session. The parameter name ("Name") is optional, and wildcard characters (*) are permitted in the value.

<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.

 

Inputs

System.Management.Automation.PSSnapInInfo

You can pipe a snap-in object to Remove-PSSnapin.

Outputs

None or System.Management.Automation.PSSnapInInfo

By default, Remove-PsSnapin does not generate any output. However, if you use the PassThru parameter, it generates a System.Management.Automation.PSSnapInInfo object representing the snap-in.

Notes

You can also refer to Remove-PSSnapin by its built-in alias, "rsnp". For more information, see about_Aliases.

Remove-PSSnapin does not check the version of Windows PowerShell before removing a snap-in from the session. If a snap-in cannot be removed, a warning appears and the command fails.

Remove-PSSnapin affects only the current session. If you have added an Add-PSSnapin command to your Windows PowerShell profile, you should delete the command to remove the snap-in from future sessions. For instructions, see about_Profiles.

Example 1

C:\PS>remove-pssnapin -name Microsoft.Exchange

Description

-----------

This command removes the Microsoft.Exchange snap-in from the current session. When the command is complete, the cmdlets and providers that the snap-in supported are not available in the session.

Example 2

C:\PS>get-PSSnapIn smp* | remove-PSSnapIn

Description

-----------

This command removes the Windows PowerShell snap-ins that have names beginning with "smp" from the current session.

The command uses the Get-PSSnapin cmdlet to get objects representing the snap-ins. The pipeline operator (|) sends the results to the Remove-PSSnapin cmdlet, which removes them from the session. The providers and cmdlets that this snap-in supports are no longer available in the session.

When you pipe objects to Remove-PSSnapin, the names of the objects are associated with the Name parameter, which accepts objects from the pipeline that have a Name property.

Example 3

C:\PS>remove-pssnapin -name *event*

Description

-----------

This command removes all Windows PowerShell snap-ins that have names that include "event". This command specifies the "Name" parameter name, but the parameter name can be omitted because it is optional.
