I had a meeting with Microsoft this week. They told us Windows 10 is the last version of Windows desktop as a product. They will release updates twice a year going forward much like Apple does for OS X. Windows desktop is now a service.
Yep, and they'll move it into the cloud if they can figure out how.
Actually the "last version of Windows" mantra is BS. They're just substituting the word "update" for "release". Apple did the same thing, more or less, many years before that. It's just Marketing's answer to the fact that most customers DO NOT like to change major releases -- it's scary for a lot of reasons. But "updates" sounds more friendly, less scary.
