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?

Unplug the inputs. Control-Alt-Delete and Winkey-L are kernel level hotkeys and cannot be overridden, you can't build an application to do this if you're attempting to protect against malicious users. –  Phoshi Jul 2 '13 at 12:57

There is no real easy way to do this programically, however there is third party software available called DesktopLock. I have never used it personally, but it sounds like what your looking for

It would be awesome but it is shareware. I prefer a freeware or open source solution. Thanks anyway! –  papaiatis Jul 2 '13 at 13:28

A bit different approach, but it meets your requirements - the screen is always enabled and password is required to do anything.

Unplug keyboard and mouse from that PC and install a VNC server on it. You'll be able to connect to it and control it from any other PC on the network. Server can be set up to require password to accept connection.
