There's another angle to this. What if Microsoft created a new linux-based OS precisely to start from scratch and let go of all the Windows cruft? Windows 10 is mature enough to not need any significant work and still maintain backwards-compatibility, but maybe Microsoft is preparing the terrain with a new OS for the next 20 years. Apple is moving fast towards universal apps for mobile and desktop. Maybe Google is doing that with Fuchsia too. Microsoft failed with Windows Phone but it probably learned from its mistakes. I'd be surprised if Windows 10 + Android is their long term goal.
