According to an anonymous source who goes by WZOR (and who has been behind numerous Microsoft leaks in the past), Windows 9 will see the light of day in 2014. No other details were provided, other than the claim that Aero would be making a comeback in Windows 9 after disappearing in Windows 8, since it was a hot feature that many avid Windows users missed.
Details on Windows 10 were also provided, with claims that the future operating system will be a “cloud OS,” meaning that all of the processing and computing would be done on Microsoft’s servers, and be streamed to your computer, completely eliminating the need for a powerful rig and only requiring the basic bits to run peripherals and such. Windows 10 would essentially just be a new cloud service for Microsoft, on top of Office 365 and the new Xbox Cloud on Xbox One, pushing the company further into the cloud ecosystem.
