Children are fascinated by computers. Maybe that's because of the bright, colorful screen. Or maybe it's because they see you working on yours.
Of course, you really don't want your child messing with your computer. Your data could be gone in seconds. Or, your settings could be altered.
So, if you have a toddler, you might want to install Keyboard Cleaner. This program will lock your computer keyboard.
When you want to use your keyboard again, press the shortcut key. It is displayed on the screen as a reminder.
Of course, Keyboard Cleaner isn't aimed primarily at kids. It will keep you from pressing the wrong keys when you're cleaning. That way, you don't have to power down your computer!
