Ctrl-Alt-Del in Hyper-V and RDP
Periodically I have to look this up again, so I’m putting it here for future reference and for anyone else who needs it.
To send Ctrl-Alt-Del to a remote desktop (RDP) session, press Ctrl-Alt-End.
To send Ctrl-Alt-Del to a virtual machine when you are RDP’d into the Hyper-V host, press RtCtrl-Del. You must use the right-hand control button.
