Easy Lock is a software intended to control what users can or cannot do with their desktops. It covers security from logging on, user control, down to process control, securing the desktop watertight.
You can set for each user group exactly what they can or cannot do on their desktops. The software really shines in production enviroments, schools, internet caffes and everywhere where desktops are meant to do an exactly pinpointed job.
The best part is that it takes only 10 minutes of your time to set up, and leaves the system in the same state as it was before installation, when you uninstall it.
