What's the difference Microsoft Xbox one and Xbox one?

They're both made by Microsoft so there wouldn't be any different with that. The only difference would be if you see it followed by an S or X as well.

Xbox one s and newer lacks the power brick

First gen Xbox one can't be repaired because lack of parts

Backwards compatibility is a feature or which I'm really grateful to Microsoft to make it happen. This is one feature I think no one thought will be there when Xbox One was launched. This may be the reason the stores for different generations ar different
and this is what i can live with.

The One S is going to be a little smaller and supports 4K. That's really the only difference. Unless you're using it for it's 4k capabilities, it's really not going to be better than the One.

Hey there.

It sounds like you used a different Microsoft account with the profile on your Xbox 360 than what you used on your Xbox One. You may want to try signing in with a different e-mail address on your Xbox One. Unfortunately there isn't an option to combine your
accounts. But if you set your Xbox One as your home Xbox for NativePhoenix92, MissMadness1 should have access to any content or subscription.
