Microsoft is a big company, that's a different team with a different set of leadership. The guy in charge of Windows stepped away. Windows 10 is the last version of Windows basically. Not sure if that means someday they may release a distro (crazy I know) but it's interesting nonetheless.
I know about that one, but I mean one that'd be consumer driven in some way. I know the ship has sailed but I'd love to see Microsoft create an Android / iOS competitor, and maybe something open source would give them an edge in that regard. It would be best if it were somehow privacy / security focused. Microsoft has the resources to make amazing products the issue is and I've mentioned it before, the company is ever so big, with ever SO MANY PRODUCTS and projects. We know they've got quite a bit going on on the user facing front, but I can't imagine how many internal tools they've got that they rely on as well.
