And as you’ve seen, when you use Remote Desktop to get to your machine, the “Turn Off Computer” item is missing from the Start menu. To be honest, I’m not really sure why Microsoft chose to do that, it is inconvenient.
But we have ways.

I previously recommended using a copy of psshutdown from the folks over at Sysinternals.com. This is a command line tool that will allow you to shut down or restart a computer remotely. It actually has several options to control how quickly, whether to force running applications to close, and so on. It’s quite handy for batchfiles and to create shortcuts for shutting down.
Another approach doesn’t involve downloading any additional software. As it turns out Task Manager already has what we need.
On the remote machine, right click on the clock, and select Task Manager. Task Manager has a Shutdown menu, which includes items to Turn Off and Restart. Those do the same thing as the missing Start Menu items.
