Its a FN key, which basically means its hard wired to the controller.
What you could do, if you REALLY wanted the FN key to be a windows key, is jump the switch from the right windows key. It wouldn't act as a left windows key, ( windows sees that as two separate keys ) but it would do the job. And ofc, you'd loose your FN key. ( unless you cross jumped them to make the right windows key the FN key )
