There are too many articles to make Apple Magic Keyboard 2 to work on Windows 10 with Function keys (volume etc).
None of them explain how to do it on windows machine that is not running o non-apple hardware and if there are - none of the method worked.
Simple steps, without a foreplay:
Magic, sound controls work as expected, fn key switches to functions etc. No changes in device manager device name, but that doesn't bother me.
