This could be a future service primarily targeting business users. The original source is Brad Sams at Petri.net (who is also a partner with Paul Thurrott at Thurrott.com) who found the info in MS job postings. I blogged about this for Win10.Guru last Thursday: Rumors Swirl About Microsoft Managed Desktop. Interesting situation, but not a paradigm shift for Windows, either.
