mLock will block access to your PCs desktop. It blanks the screen and requests a password to unlock it. It disables the Windows key, alt-tab, ctrl-esc and even ctrl-alt-del is crippled.

Caution! Don't forget the password you set because your only solution is to reset your PC. The default password is: 0000. You can change the password. The new one is saved (encrypted) in the MyLock.cfg file. Use this batch file to add mLock to your system registry, so it starts with Windows before user can do anything.
