PowerShell contains a default set of snap-ins containing the built-in providers and cmdlets.
In PowerShell 1.0 these default Snap-Ins are:
Microsoft.PowerShell.Core = components of PowerShell.
Microsoft.PowerShell.Host = Start-Transcript, Stop-Transcript etc, managing PowerShell console host.
Microsoft.PowerShell.Management = management cmdlets used to manage Windows components.
Microsoft.PowerShell.Security = cmdlets to manage Windows PowerShell security.
Microsoft.PowerShell.Utility = utility Cmdlets used to manipulate data.
PowerShell 2.0 adds to the above:
Microsoft.PowerShell.Diagnostics = Eventing and Performance Counter cmdlets.
Microsoft.WSMan.Management = Get-WSManInstance, Set-WSManInstance etc for WSMan operations.
Installing a Snap-In requires Administrator rights.
Beginning in PowerShell 2.0 Modules were introduced and they almost entirely replace Snap-Ins.
Snap-Ins are still available and fully supported. Snap-Ins have to be installed, modules can be simply copied and then made available with Import-Module
Equivalent commands for Snap-Ins and Modules are shown below:
Get-Command -pssnapin name
Get-Command -module name
Get the Windows PowerShell snap-ins that are currently loaded:
