Hello, honestly just forget about remapping the Copilot key. I've spent hours on this, and my workout which is working perfectly for me has been to remap the Right Alt key instead to Ctrl key. Don't worry about remapping shortcuts bla bla bla, it doesn't work. Trust me, using the right Alt key is the best workout to this horrible thing that Microsoft has done to us lol
Check out my post from today if you want full instructions. I still used PowerToys. LMK if it works for you.
