That new Windows 10 Xbox One update sounds pretty great, right? Well, how it works is a little different than folks in the console's Dashboard Preview Program are used to. Previous updates were pushed out automatically and you had no choice over installing them, but here you can choose as to whether or not jump into this massive overhaul. Xbox spokesperson Larry "Major Nelson" Hryb says that Preview members will get a message in their system's inbox and you'll need to register and opt-in from there. But if you're not quite sure about being even more of a guinea pig that's totally okay: You can choose to not participate in the double preview and still get the regular dashboard updates ahead of the general public.
