Keylogger Lite keeps accurate records of all keyboard activity once you have installed and started the program. You can set the program to run at Windows Startup and you can run it in Active Monitoring Mode. The program is quite simple. Hit "Start" and the program will monitor any key strokes, including "Shift", "Ctrl", "Space" etc. keys and will create a log containing the date and time, window title, keys pressed.

Drawbacks / flaws: When running, the program's icon stays visible in the tray, so that you cannot secretly monitor activity on a certain machine.

In conclusion: Simple and effective, but few extra features.
