Definitive list of Windows Server installations without GUIs
‘Server Core’ has been around for quite a while. Roughly for as long as this domain exists (registered on January 19, 2008, while Windows Server 2008 was released on February 4, 2008).
About Server Core
Server Core is a significantly scaled-back installation and/or run type for Windows Server where no Windows Explorer shell is installed. All configuration and maintenance is done entirely through command-line interface windows, or by connecting to the machine remotely using Microsoft Management Console. However, Notepad and some control panel applets, such as Regional Settings, are available.
Microsoft’s primary motivation for producing a Server Core variant of Windows Server was to reduce the attack surface of the operating system.
List of Windows Server versions
A question I get regularly is which Windows Server versions can be run without Graphical User Interface, which Windows Server versions come without a GUI and which Windows Server offer the Server Core installation option.
The list below serves as the definitive list of released Windows Server versions.
It will be updated when Microsoft releases new versions of Windows Server.
