You'd think nothing happens when you hit the copilot key, but instead, it... pops up the settings window so you can select what should happen. Not the most awful thing, but really, I want nothing to happen, period. That's why I hit "none selected" instead of "Open an app" or "Search".
TBF PowerToys is first party, so most companies will accept its installation. It has many other niceties that should really have been baked into Windows in the first place, I genuinely think all windows users that care even a bit should have it by default as one of the first thing they put on their system.
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.
