Ever try to restart a machine via remote desktop? I just ran into it for the first time tonight. I generally deal with linux servers and don’t ever RDP into them. Tonight, I needed to reboot a windows server. No “shutdown” exists on the Start menu. Even on the task manager, there’s no shutdown option.
It’s an easy bypass though.
Instead of CTRL+ALT+DEL like usual, use
From here, you will be able to shut down or graceful reboot the system.
