In Server 2012 there is a install feature called Minimal GUI that removes Windows Explorer and Internet explorer. You get a GUI but only server manager and a dos prompt. In my case a new VM had too small of resolution, and in MinGui you cannot open control panel, or right click to change it.
PowerShell to the rescue:
go to the DOS window
Type PS to enter PowerShell
Type Set-DisplayResolution -width 1440 -height 900 -force
