I'm doing it right now. Everything works, except one little annoyance: when I press "Win+L" combo to lock PC, the "Win" key remains pressed until I hit it again. The same situation after I enter the password to unlock PC. Can be anything done to get rid of this? Maybe there exists a lower-level key remapping facility in Windows 7?
It is a nice piece of software that remaps your keyboard by altering the registry. Been using it for a long time to switch Caps/CTRL.
