"Microsoft is working on an operating system based in the cloud apparently called Windows Cloud. The client software would be available to users as a free download, and it might resemble earlier Windows Starter editions. More advanced features would then be available only when a subscription is purchased, and it would require an active Internet connection.In offline mode, the OS would only include basic functionality." For many an OS based on the cloud partly could be acceptable but an OS based fully on the cloud isn't. So may be we might have to migrate to Ubuntu or some other Linux distro.
Like Windows 8 and its crappy Microsoft account wasn't enough!
