I personally wrote the program that does all the steps necessary to remap the Copilot key, since it's actually three keys (Left Windows, Left Shift, F23), it's not as simple as it sounds to block all those keypresses while also allowing the real keys through.

You could also call it "I changed your copilot key back to Ctrl".

This program does properly allow you to use the left shift key completely independently of the remapped copilot key, many similar programs do not have this feature.
