The next version of Windows has a tentative release date of April, 2015. This is according to Paul Thurrot, owner and operator of Winsupersite.com, one of the biggest and most reliable online repositories of all things Microsoft outside of Redmond itself.

Tellingly, he calls the next version of Windows a “make or break” release for Microsoft as a result of the disappointing Windows 8, which he says “is tanking harder than Microsoft is comfortable discussing in public”.

In the post he mentions that Microsoft is expected to make major announcements about Windows 9 at April’s BUILD conference, including “its first major ‘vision’ announcement for Windows since, yes, Longhorn [Windows XP] in 2003”.
