Changing the available cmdlets and providers by adding or removing snap-ins will only affect the current console.

After a snap-ins has been added, you can use the cmdlets and providers that the snap-in supports in the current session. To add the snap-in to all future PowerShell sessions, add an Add-PSSnapin command to your PowerShell profile.

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 copied (like a script) and then made available with Import-Module

Beginning in PowerShell 3.0, the core PowerShell cmdlets 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 or you can use Import-Module to import them.


Add the Microsoft Exchange and Microsoft AD Directory Services snap-ins to the current console:

PS C:> add-PSSnapIn Microsoft.Exchange,Microsoft.Windows.AD

Add all the registered Windows PowerShell snap-ins to the console:

PS C:> get-pssnapin -registered | add-pssnapin -passthru

Save the console configuration

To save the configuration of the current console, (including any extra snap-ins that are loaded) to a (.psc1) console file use Export-Console.
PS C:> export-console C:\SS64.psc1

Restore the console configuration

To open a PowerShell console with a saved console configuration, start PowerShell with the -PsConsoleFile parameter.

PS C:> powershell.exe -psconsolefile C:\SS64.psc1
