Screen Lock is a very simple application whose purpose is to lock the screen of computers running under Windows XP.
It comes in handy whenever you want to leave your workstation unattended, in order to prevent pry eyes from looking into your personal information.
The installation procedure is rapid and uneventful. A system restart is automatically launched at the end of it, but Screen Lock does not warn the user about this.
You can access Screen Lock through a desktop icon, Start menu entry, or other option you have selected in the installer.
At the first run you are required to specify the password that will be used to unlock the screen. In locked state, Screen Lock displays a dummy Windows XP wallpaper. There are no other options available through this tool.
The application is light on the system resources, running on a small amount of CPU and memory. It has a good response time to commands and doesn't cause the operating system to hang, crash or pop up error dialogs. Too bad it has not been updated for support with newer operating systems.
