I'm looking for a windows application that locks the screen but doesn't go to the windows login screen. It would only lock all the inputs such as keyboard and mouse but it would keep the screen on. The app would unlock the screen by pressing a key combination that would pop up a password dialog.
I would like to use it for a big LCD TV which is attached to a PC that is running a live website. The PC is located in a room where 10+ people work. I don't want them to be able to use the PC without the password to unlock.
Is there such an application out there?
