It's not working for me in Windows 10. Windows does not recognize it as an Xbox Controller in Game Controllers and Steam won't recognize it at all. Replacing a Series S controller that still works when I try it, analog is just super sloppy. Have ran windows update and Xbox Accessory App does not recognize Bluetooth.
So it's really a mixed bag but at day of release, it's not working for me at all and is useless compared to the Series S controller that works fine.
