What happens if you install Windows Server 2012 without the GUI features and then realize that you want to turn on the GUI? For those who are used to GUI based Windows Server administration, seeing a command line interface can be daunting. This guide will help you to go from the command line interface, using PowerShell, to installing and turning on the GUI.

You will see a text based installer. This part of the Windows Server 2012 GUI installation is rather easy and there is plenty of time to grab a drink.

If you are accustomed to the Windows Server 2012 GUI, you may be a bit nervous seeing a command line only interface. Fear not, the guide above uses less than 90 characters of typing to install and turn on the GUI. In total this took me only a few minutes to do the run-through. Also, this guide assumed one has a command line only installation. If you already have the GUI installed, you can use SConfig to turn on the GUI easily.
