As Microsoft prepares to make a big reveal tomorrow, January 21, of the new consumer features coming to Windows 10, new word from Mary Jo Foley from ZDNet indicates that the software maker will not release a preview version of Windows 10 for mobile devices follow the event.
Instead, it appears, that the first preview of the Windows 10 SKU for mobile devices will release sometime in February 2015. However, Microsoft still expected to talk and demo the mobile operating system during the press event.
Windows Phone 10, also known internally in Microsoft as “Windows 10 Mobile”, will work on smartphones and small tablets based on Intel and ARM processors, and it’s likely not to feature the desktop environment.
Perhaps the biggest piece of information with today’s news is that Microsoft will highlight that Windows 10 is built on a single, unified core, which is internally known as “OneCore”. Basically, it’s a single version of the Windows kernel that works across devices including PCs, tablets, phones, and other form factors, even on Xbox, eventually.
But it’s not just the core like we see today with Windows 8 and Windows Phone 8. The OneCore for Windows 10 also includes dynamic link libraries (DLLs), application platform layer, and other pieces of the operating system. The advantage of a common core across platform is that it will allow developers to create Windows 10 Universal apps that works on all the range of screen sizes supported by the operating system. These apps will be available on the new unified Windows Store, rather than in separate stores like we see today.
Just to be clear “OneCore” doesn’t mean “One Windows”, or a single SKU of Windows 10. Although, Microsoft is expected to refer every version of the operating system as “Windows 10”, you’ll still see a multiple variants of the operating system with different prices and licensing model.
