Server Core

Server Core is  just a installation option - no special edition.

Advantage of Server Core

  • Uses less ressources
  • Uses less disk space

  • More secure to attacks

With Server Manager and other tools, administrators can install a server using the server core option, join these into existing domain via PowerShell and never touch the console again. All necessary tasks can be run from a remote workstation.

The Minimal Server Interface

The Minimal Server Interface consists of the program an the prompt (as you see in Server Core). To activate the Minimal Server Interface make sure that only the Feature "Graphical Management Tools and Infrastructure" is installed. The following video shows how to change between the different options.

Features on demand

Windows Server 2012 has its features in the so called side by side directory, usually C:\Windows\WinSxS. With features on demand administrators can activate any of the features without supplying a installation medium. The disadvantage of it is that the WinSxS Directory is very large. If you are running out of space, perhaps because if you are using SSDs, you probably have to reduce the amount your installation is using. You can deinstall features via Powershell.

CBT Nuggets have a really good video for this here
