How can I remap keyboard keys in windows 8.1? I'm looking for a simple utility which will modify registry and would not require running at startup. I tried sharpkeys but, it does not seem to work in windows 8.1. Any other suggestions? Or a simple how-to tutorial for windows 8.1?
Edit: Keytweak isn't working either. Actually I want to map an unused key to function key (fn) and neither sharpkeys nor keytweak detect the keystroke for that key.
