While Microsoft is seemingly busy fighting for a bigger share for Windows 8.1 on the tablet market, its developers have already started working on the next generation of the operating system.
According to Paul Thurrott, editor of Winsupersite, the new version (running currently under the codename Threshold) will be out in 2015 as Windows 9. According to the article, the new Windows 9 will be presented on Microsoft's annual Build developers' conference in April.
While the source code will not be given to the developers yet, Microsoft will allegedly totally reinstate the Start menu, and the new Windows 8 apps will be able to run in desktop windows, just as any other application.
"It's an acknowledgment that what came before didn't work, and didn't resonate with customers" - says Thurrott, suggesting that Windows 9 recasts Windows 8 as the next Vista, the famously bad Windows version that needed to be quickly fixed by Windows 7, a much more successful successor.
