Examples

Example 1: Remove a snap-in

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

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: Remove snap-ins by using names with the pipeline

PS C:\> Get-PSSnapIn smp* | Remove-PSSnapIn

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

The command uses the Get-PSSnapin cmdlet to get objects that represent 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.

PS C:\> Remove-PSSnapin -Name *event*

This command removes all Windows PowerShell snap-ins that have names that include event.
