Using Server Core
The Server Core interface is a command prompt with PowerShell support. In Windows Server
2012 or 2012 R2, you can transition between Server with a GUI mode and Server Core mode
without reinstalling the operating system.

PS C:\Users\Administrator> Remove-WindowsFeature Server-Gui-Shell,
Server-Gui-Mgmt-Infra

After the server restart, only the command prompt will be available, indicating the server is
