In Windows Server 2008 R2, you have to choose whether you want server core (the no GUI version) or Full installation (with a GUI).
In Windows Server 2012, the GUI can be installed or uinstalled at will even after the server has been stood up. Plus, at setup, the GUI will not be turned on by default. You actually have to tell the OS that you want the GUI.
Start learning your Powershell, folks.

I'm not learning Powershell and your post makes no sense.
