Scan codes can be edited in the system registry to map one key to another but editing the registry manually is tricky. When you press a key on the keyboard it sends a “scan code” to tell Windows what has been pressed. More advanced users could turn to software such as a Macro tool which can help you remap keys on a keyboard or even perform more complicated tasks for you, or run a shortcut/hotkey utility. Whether it’s disabling the key or making it perform another action. In all those situations, a simple solution would be to change the keyboard keys to do something else. Or, there might be a key on your keyboard you never seem to use or need.

Maybe there’s keys you keep hitting by mistake such as Caps Lock, or would just like a certain key to be in a more convenient location. Although it’s not a terrible problem if the keypress still registers without the key, it is quite difficult if a common key doesn’t work at all. Broken keyboard keys are quite a common occurrence on laptops and netbooks.
