I can recommend “Sharpkeys”, as it works pretty good with Win 10 and an Apple wired keyboard, using it for about +6 years already, since Vista-Win 8 and now Win 10. It does not require any intallation as it remaps keys on registry level.
Bear in mind, as I still haven’t received my V, I have not been able to test it with it.
I personally do not use the Win Key on any keyboard and have it remapped as Alt key due to being close to Ctrl key and that combination is my daily professional use CAD, Photoshop etc.
Why not leave the Fn key of the V where it is, as it was mentioned it is mapped on a hardware level and instead, map the Win key as a left CTRL key, this way even better the Ctrl+Alt combination is even more legitimate.
If someone would like to visually make it perfect, perhaps they may swap the hardware key caps too, as I assume the key sizes and snap hinges underneath are the same.
