Server 2012 Core How To Shut Down

With seemingly so few options in Server Core, how do you easily shut a system down?

If you have the command window open, you can use the shutdown command. I forget the switches though.

My personal preference is to use the Powershell command Stop-Computer.

If you've lost the command window, you can get it back again. Simply press Ctrl-Alt-Esc to launch task manager.

From there, you can run any program, so just run cmd.exe. Voila, you have your command window back.
