Modules are a set of commands that can be added to Powershell as well as Snapins.

For a list of available modules, use the command :

PS C:> get-module -ListAvailable

Manifest ActiveDirectory {}
Manifest ADRMS {}
Manifest AppLocker {}
Manifest BestPractices {}
Manifest BitsTransfer {}
Manifest GroupPolicy {}
Manifest PSDiagnostics {}

Some modules are installed automatically during installation of features on the server, as is the case with Active Directory and GroupPolicy that are installed with a new Domain Controller.
