Normally I hit the power button until it turns off/reboots. This sucks as i have to wait 10 minutes to get everything reloaded. Is there some other shortcut I could do? The last user is on afternoons so I can’t just ask him to sign in and logoff.
You would need to get someone with Administrator privileges to log him off.
I’m running Windows 7 so this is just from memory, but if you click on the windows button, just as if you were going to shut down the system properly, should be “log off.” I don’t believe this requires a password. It should take you to the normal log on screen you see after a cold start.
The OP says “I can’t just ask him to sign in and logoff”, so presumably the screen is locked.
ETA: I’m guessing the “ShutDown” button is greyed out also, or else he’d use that instead of the power button. Not that that would be any quicker.
