Two weeks before the launch of Windows 8 Microsoft confirmed it had already started the development of the next Windows version – known as Windows 9 as of now.
There’s virtually very little information on the new OS but analysts expect it is still in early stages of development. Windows 9 has, however, become the main development object of Microsoft’s efforts.
Additionally it has become known that Windows Blue is not the codename for Windows 9 – instead Windows Blue is the codename for an upgrade version of Windows 8. It is however unclear as to what kind of an upgrade this will be.
Microsoft has not released any details on Windows 9, including a possible release date but analysts expect Windows 9 to appear within the next 2-3 years.
