Microsoft announced that users who own Windows RT, inclusive of those who own Surface RT tablets, would not be able to update to Windows 10. The company has however been working on an update for the Surface and Microsoft and finally revealed that the update will be coming to RT users in September, according Microsoft’s Gabe Aul.
The update is dubbed the Windows 8.1 RT Update 3 and so far we are not so clear as to what are the functionality provided but there will more information soon.
Basically, Windows RT is already dying as there are not much support available for it and few OEMs are still making tablets with the OS. We'll have to see whether the update will be some consolation for early Surface adopters.
