Ever wondered where you accounts file disappeared after you “still learning computer” kid got off from the system ? Accidents happen and you can blame anybody for accidental copy, paste, delete for making you file sending them to black hole.
Prevent, developed by Ritesh Kawadkar, is a simple application which allows you to disable such keys including task manager and context menu item which appears on right click. Though this might not be a necessity but if you see files missing after somebody else uses your computer, prevent can do a good job for you.
