I have solved it... but its not for sale :P MS hasn't solved it. And they aren't even close. They need a visionary. In short, they need someone like Steve Jobs. Someone with an iron-hand who will overlook everything, and bring everything cohesive and together. They basically need one UI that works for things from watches, phones, tablets, laptops, all-in-ones, to TV's. MS wants that but is far off. (Band, WP, RT, W10, XB1) Apple is closer to that. (Watch, iOS, OSX, A-TV) But the closest is Google. (Wear, Android, Chromium, TV)
