It looks like Windows RT and Windows Server 2012 will be included in the Windows 8.1 update. The operating system update, code named Windows “Blue,” has been rumored to be for an entire line of Windows products so this leak makes sense. The leaked SKUs were found in the recently released 9374 build of Windows 8.1 where a .dll file mentioned “Windows RT 8.1 Preview” and “Windows Server 2012 R2.”
With the official launch of Windows 8.1 still months away, there’s no solid information about what the updated operating system will bring. Still, there have been a flurry of rumors about features like Windows 8.1 bringing back the Start Button and improved multitasking with “Metro” styled apps.
Microsoft is expected to officially announce Windows 8.1 and other “Blue” products during its 2013 Build conference in San Francisco, which takes place June 26th to 28th.
