I am configuring a computer that will be hooked into a video conference system and needs to be on all the time. This pc has a special local user account, so we dont want anyone logging out, or switching user. we also don't want the computer to be locked, hibernate, sleep, or shutdown. I switched the power button to 'Restart' (computer automatically logs into user account). However, I am wondering if there is a way in the registry, or some other message, to delete the arrow, power button menu so the user has no other option besides RESTART?
