Just installed it now and the X1 controller is connected on my PC with W7
Was worried about W7 support, but some of the comments tell you how to get it working.
Sadly seems rumble support isn't on yet... or at least I don't have a way to check it which is a shame, but at least I can actually use it now.
As others have said for DS4, I think it is great, but does have compatibility issues with some games, MGR/RE6 are two examples I can think of where it doesnt work.
Gonna test some games now and see if it all works OK
