So you can’t find Shutdown Restart and Logoff. If in doubt try Server Manager … or PowerShell.
Server Manager > All Servers > Right Click your server > Shut down Local Server
PowerShell is also easy. Just use the following.
shutdown –l - LOGOFF
shutdown -s –t 0 – SHUTDOWN NOW
shutdown –s –f –t 0 – SHUTDOWN NOW FORCE
shutdown –r –t 0 – REBOOT
shutdown –r –f –t 0 – REBOOT NOW FORCE
shutdown -? – for more options
So this is not what you want, you can also add tiles to the start screen.
Import this module using PowerShell and follow this video if needed …
