I had been playing with the idea of making the jump to windows 10 from 7... this has just put that idea on hold.
as for the wireless adapter not turning on go into your device manager and turn power saving mode off that stopped that issue for me.
Is it still worth buying an xbox one controller? I have a 360 controller but I like the idea of the vibrating triggers.
I removed all drivers, disabled fire wall, inserted wireless adaptor into back of PC and suddenly it sprang to life and auto connected etc!
