Microsoft Quietly Rolls Out Windows RT Update
 

When Windows 10 was first announced, one of the first questions was would this upgrade be available for Windows RT devices running on ARM based platforms. The answer was no, but Microsoft said that it would bring some of the functionality of Windows 10 to Windows RT users though an update sometime after Windows 10 shipped. Apparently that day was yesterday, as Microsoft pushed out patch KB3033055 which enables the Windows 10 style Start Menu in Windows RT.
