It can begin to escape its legacy prison
Good luck with that. Microsoft's only real platform is the desktop now and all those "innovative" voice-activated and data-mining gadgets aren't going to be running on the desktop or even on a hybrid tablet. Their only market is the legacy market - but it's a big market and it's going to be around for a long time if they want to serve it.
Gradually turning Windows into a desktop version of Android sounds more like desperation than innovation.
