There may be situations in which you need to use the graphical user interfaces available in Server with a GUI mode. You can switch the system to Server with a GUI mode by following the steps below, although a restart is required. For more information about the differences between Server Core mode and Server with a GUI mode, as well as information about the Minimal Server Interface and Features on demand, see Windows Server Installation Options.

To convert from Server Core mode to Server with a GUI mode when the server was initially installed in Server Core mode

Determine the index number for a Server with a GUI image (for example, SERVERDATACENTER, not SERVERDATACENTERCORE) using this cmdlet: Get-WindowsImage -ImagePath \install.wim

Run Install-WindowsFeature Server-Gui-Mgmt-Infra, Server-Gui-Shell –Restart –Source wim:\install.wim:

Alternatively, if you want to use Windows Update as the source instead of a WIM file, use this Windows PowerShell cmdlet:

Install-WindowsFeature Server-Gui-Mgmt-Infra,Server-Gui-Shell –Restart
