What it does
Gets the Windows PowerShell snap-ins on the computer. The Get-PSSnapin cmdlet gets the Windows PowerShell snap-ins that have been added to the current session or that have been registered on the system. This cmdlet lists the snap-ins in the order in which they are detected. Get-PSSnapin gets only registered snap-ins. To register a Windows PowerShell snap-in, use the InstallUtil tool included with the Microsoft .NET Framework 2.0. For more information, see How to Register Cmdlets, Providers, and Host Applications. Starting in Windows PowerShell 3.0, the core commands that are included in Windows PowerShell are packaged in modules. The exception is Microsoft.PowerShell.Core, which is a snap-in (PSSnapin). By default, only the Microsoft.PowerShell.Core snap-in is added to the session. Modules are imported automatically on first use and you can use the Import-Module cmdlet to import them.
