1st Screen Lock is a password-protected desktop security utility that
lets you lock your desktop with a password on boot, or at the time you
are leaving your PC. You can use the built-in spy utility that works in
background and enables you to spy on your PC users by fixing all user
moves in a log file. This is very useful, when you need to know what
your children or personnel do at the time you are away. Each user of
1st Screen Lock has its own password used to unlock locked PC. Password
protection works in such a way that your users are unable to see user
statistics, change options, or remove the program itself, they can only
unlock PC using their own passwords.
