During its highly-anticipated Windows 10 event yesterday, Microsoft announced that the latest iteration of its operating system will be coming to the entire Surface Pro lineup, but unfortunately, will not be coming to Surface devices that are running Windows RT. 

Microsoft unveiled its plans for a free copy of Windows 10 for Windows 7 and Windows 8.1 users yesterday, but it looks like Windows RT is being left out in the cold. In a statement provided to The Verge, Microsoft confirms the Surface Pro 3 and “entire Surface Pro lineup” will get the update to Windows 10, but Windows RT won’t get the full OS. “We are working on an update for Surface, which will have some of the functionality of Windows 10. More information to come,” says a Microsoft spokesperson. This means tablets like the Surface RT and Surface 2 won’t get Windows 10.
