There can be many instances when you want to disable your mouse or keyboard temporarily without shutting down your computer. For instance, you don't want your kids to press the keyboard or mouse when you move away or you might want to clean your keyboard while the computer is powered on.

Here is a free utility called Child Lock with which you can lock your keyboard and mouse easily. Once locked, all keyboard actions and mouse clicks will be disabled.

For locking, you can either click on the lock button or press ALT+END. Unlocking can be done by pressing ALT+HOME keys.

Child Lock also has an auto lock feature which can lock the keyboard and mouse after certain time of complete inactivity.

The advantage with Child Lock is - your screen remains unchanged after the mouse and keyboard is locked. A nice feature when you are giving a video presentation and don't want annoying hands to accidentally fall on your mouse or keyboard.
