Matrix Screen locker

Matrix Screen locker is a tiny application which allows you to seamlessly lock your computer with a password. It can be easily installed and configured, even by less experienced users.
This type of tool can come in handy the moment you share your computer with multiple users, since it can protect your sensitive data.
Once initialized, the app places an icon in the system tray area. By opening its context menu, you can set up a password, as well as change it at any time into something else.
From this menu you can also make Matrix Screen locker automatically run at system startup, as well as lock the workstation. When the tool is active, a screensaver inspired from 'The Matrix' movie is displayed - the famous falling green code. If you want to unlock the computer, simply click any area of the screen and input the correct password.
The lightweight program does not put a strain on the computer's resources, since it requires a very low amount of CPU and system memory. It is very responsive to commands and worked smoothly during our tests; we have not come across any error dialogs and Matrix Screen locker did not freeze or crash.
The biggest disadvantage of the tool is that is does not incorporate keyboard shortcuts, in order to quickly lock the workstation. Unfortunately, Matrix Screen locker has not been updated for a pretty long time.
