If you never want to use the Caps Lock key again, you have plenty of other options: You can disable or remap any key in Windows, use TabsLock to make it launch your browser, turn it into a dedicated minimize button, or just neuter it with a quick autohotkey script. If you're really feeling geeky, you can learn how to disable or remap Caps Lock using a registry hack instead.
