Besides Windows 9 Microsoft is also working on Windows Cloud. According to WZOR there is a group working on a prototype operating system where the client software will be free to download and additional functionality requires a subscription.
This is sounding suspiciously like trusted/treacherous computing. Microsoft seems to be aiming for maximum control over its customers' computers. Next they'll be saying that downloading third-party (ie those not made by Microsoft) programs is dangerous/wrong because they might contain malware, or they might be tools meant for "piracy". That's what Microsoft will say about Libre/Open Office.
This reminds me of an amusing cartoon I once found depicting a Microsoft employee who came up with an idea: "It's a brand new concept, sir. Rather than designing programs based on what users want, we can design users based on what the programs want."
