Child Proof: Child Proof is a program that protect your computer from children by accident pressing wrong buttons or key. It hides all windows, the toolbar at the bottom and the desktop and replaces it by a toolbar with programs you allow your child to execute. This avoids most problems when children use the computer. The default exit key to exist from the locked screen is CTRL + ALT + Shift + P. This combination can also be changed in Options. Child Proof is unable to disable the power button and CD/DVD eject key but it can allow programs such as games to be played.
