You can disable the caps lock key in Windows by editing the HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlKeyboard Layout registry key. Here, you’ll see Scancode Map, which should be set to the hex value of 00,00,00,00,00,00,00,00,02,00,00,00,00,00,3a,00,00,00,00,00 if you want to disable caps lock. MysterCrowley.com has a number of useful little applications. One of which runs the registry hack to disable the caps lock key for you. It’s called Numlocker. Another, keyboardlink allows you to assign shortcuts in strange ways that you couldn’t otherwise assign shortcuts, also using the scancode maps.
