Windows – Powershell Servermanager module not included in Windows Web Server 2008 R2

This is driving me nuts!

Apparently using the servermanager module should be as easy as type:

Import-Module servermanager

The problem is that I don't have it.

PS C:\Users\Administrator> Get-Module -ListAvailable

Any attempt to search in Google "Install servemanager module" returns thousands of pages to install things using the servermanager module! :-\

I'm using an up-to-date copy of Windows Web Server 2008 R2 with Service Pack 1, and Powershell v4.
