After talking to a few of her sources inside the company, she’s gained a pretty decent insight into what Jupiter actually is. The Jupiter rumours were confirmed by another Microsoft insider, Mary-Jo Foley.

“The Windows and Office teams are betting very heavily on this new app type, according to my source, and development has already begun using a beta version of Visual Studio 2012,” he adds, “These apps can be written in C#, Visual Basic, and even C++.” “Windows 8 will also include a new app model codenamed Jupiter that will target a new Windows Marketplace app store,” Thurrot claims, “The app store will provide access to new, Silverlight-based ‘immersive’ applications that are deployed as AppX packages (.appx).” The rumours around Jupiter are possibly more interesting. Not only would this be a serious cost-cutting measure, but it would also allow for faster propagation of new lower-level features throughout all the different form-factors currently supported by Windows NT and Windows CE. In other words, it’s not a replacement, but an alternative.Īll this seems to fit with the idea that Microsoft is trying to consolidate all form factors into one – as in, everything will be running Windows NT, no matter the screen size, no matter the architecture.

According to Paul Thurrot, the interface is codenamed Mosh, and will only be available on devices like tablets. The tile-based interface would appear to be similar to what’s currently available on Windows Phone 7, but without any details – let alone screenshots – it’s impossible to tell. It seems like the pieces of the puzzle are all falling into place: Windows NT everywhere, Silverlight/.Net everywhere. It’s a rumour, but confirmed by different people: there will be a new application model in Windows 8, currently named Jupiter, while thee will also be a tile-based interface for tablets. Since the big Windows news last week was the announcement that the next version of Windows will run on ARM, this one kind of slipped in under the radar.
