Reboot PC via MSTSC

These next two tricks are documented and will continue to work in future versions of Windows:

If you’re a command line person, you can run shutdown.exe, but that program supports only shutdown and restart; it doesn’t do stand-by or hibernate. But the shutdown.exe program has a serious flaw: It requires you to have administrator privileges. If you are a limited user with shutdown privileges, the shutdown.exe program will complain. (Which means that I don’t use it.)

Finally, if your computer isn’t using Fast User Switching, you can type the Ctrl+Alt+End hotkey, which is the Remote Desktop version of Ctrl+Alt+Del and consequently takes you to a dialog where you can do various system-type things, among them logging off and shutting down.
