Microsoft has removed the 8.1 RT update from the Windows Store, temporarily, to address what it’s describing as “a situation affecting a limited number of users updating their Windows RT devices to Windows RT 8.1.”
Windows RT is the version of the operating system that runs on ARM-based processors, in machines including the Microsoft Surface RT tablet. The 8.1 update was released this past week.
A Microsoft Surface support engineer explains in the thread, “Microsoft is investigating a situation affecting a limited number of users updating their Windows RT devices to Windows RT 8.1. As a result, we have temporarily removed the Windows RT 8.1 update from the Windows Store. We are working to resolve the situation as quickly as possible and apologize for any inconvenience. We will provide updates as they become available.”
A forum user points to a Boot Configuration error as the likely culprit.
I confirmed on my Surface RT this morning that the 8.1 update isn’t available in the Windows Store. The situation doesn’t appear to affect the Windows 8.1 update for Intel-based machines. I’ve asked a Microsoft representative for more details.
