Windows 7 NumLocker

[loathe]

Check this out. A small application that runs in the background lets you disable caps, num and scroll lock keys and more.

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.
