Microsoft showed its plans for Windows 10 across a wide range of devices this week, but notably absent from its discussions was talk of the new operating system on ARM tablets. According to the company, it still plans to support ARM devices, but with some conditions.

Windows RT, the ARM-based operating system that powers Microsoft’s Surface and Surface 2 tablets, is essentially being discontinued by the company, as it won’t receive Windows 10. Terry Myerson, head of the operating system team at Microsoft, notably dodged the question of whether ARM-powered Surface tablets would receive Windows 10, merely saying the company was “working on an update for Windows RT.” Microsoft later clarified that the update “will have some of the functionality of Windows 10.”
Microsoft won’t entirely stop supporting ARM devices, however, but there will be conditions for what devices Windows 10 will be offered on.
