Sometimes you just need to reboot a Windows desktop over RDP...
RDP Tips
CTRL+ALT+PAUSE: Switches your Remote Desktop client between full-screen and windowed mode.
CTRL+ALT+BREAK: Force the Remote Desktop into full-screen mode.
CTRL+ALT+MINUS: Takes a screenshot of the active Remote Desktop window.
CTRL+ALT+PLUS: Takes a screenshot of the entire Remote Desktop.
CTRL+ALT+END: Reboots the remote computer.
Press CTRL+ALT+END, then click on the Power icon seen at bottom-right. These are the choices you may see, in Windows 10.I
have noticed that with Windows 10 over RDP, typing CTRL+ALT+END will
bring up the usual choice of options you get when typing CTRL+ALT+DEL.
