If on windows enter this:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]
"Scancode Map"=hex:00,00,00,00,00,00,00,00,02,00,00,00,00,00,5B,E0,00,00,00,00
*there should be no spaces*
disable left windows key only, you can still have the right one. Convenient as it gets it out of the way for gaming, but you still have one for command shortcuts.
