New Xbox Achievement UI?

As an Xbox fan, I will get it anyway, but yeah it's looking amazing, especially the ray tracing, ssd, and the new amd cpu and gpu. I can't wait to see how it looks like. I just hope there will be a new UI and controller as it is a new generation afte rall.
Love the one ui and controller, but I love the excitement of everything being new in the next generation. I still remember how excited I was day One 2013 to explore the Xbox One UI. I also hope that they will finally implement the new achievement system .
And please bring back app achievements, it was special unlocking the Xbox One Day One achievement and please make a cool Day One bundle

looking forward to these new updates. Hoping for a new UI design when the new xbox is released more tidy and unique UI would be nice to have.

It's Windows 10 like, now. Unlike previous versions which were Windows 8 like. Windows 10 is a much faster UI/OS. Xbox 1's UI was far too slow at Launch were several members mentioned it took 30 seconds just to open up an app like Messages or Friends or
Achievements. No it's not our ISP's. It's the way they make the software. With the new UI, it's faster for sure. We can click click click scroll click, rather than click.... wait..... click.... wait..... wait.... I give up

I still think Xbox 360's UI has a few advantages though. It's Xbox Guide Menu gives you quick and easy access to Party/friends/achievements/mesages without shrinking or leaving your game. Xbox 360's UI there is a page on the dashboard called Social, which
shows you and your friends avatars, and in party, shows gamertag avatars too. On Xbox 360 in the Xbox Guide Menu, you can also see everyone in your party chat. Xbox 360's UI is a bit more kiddy but for reasons mentioned in this paragraph, I still like it better.
Xbox 1's Community Page mainly, just shows activity feed.

Microsoft didn't remove all Kinect features with the new UI. We still have voice messaging. But gestures have been removed since most people didn't use it. They may bring it back later though. But the one thing that will stand out with this new Windows 10-like,
UI is IT IS A LOT FASTER than that previous Windows 8 hunk. Too me it's the best UI version they've released so far on Xbox 1.

The new Netflix update is beautiful and this new UI was created by Netflix not Microsoft. They wanted to unify the TV UI across many different devices. This new Netflix UI can be found on both Xbox 360 and PS3 for example and looks exactly the same on both
consoles.

No, what im asking is that why do i have the old ui instead of the new ui after i fully resetted my computer and why the new ui only appears on the xbox, xbox console companion and minecraft (from the in-game sign in button)
