So with the Xbox preview program I had recently Downloaded Windows 10 to the Xbox one ( beta testing ) , so I decided I wanted to switch it back to normal so I finally got an update to do just that, as a result It's like I just got an Xbox one Had to sign into my account , get the whole system set up as if I just picked it up from the store Yes I know it saves all my game data , it's just the fact I have so redownload everything with no warning There wasn't even a warning that it would restore my Xbox to factory default I'm currently keeping it on all night as it redownloads destiny and all of its content Moral of story do not go into the Xbox preview program .
