Late last week, Microsoft introduced an upgrade that moved tablets running Windows RT to Windows RT 8.1. This has been removed from the company’s web site after some of their users that had installed it reported having serious problems.
A note on the official support page for Windows 8.1 RT now says:
“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.”
This issue does not affect the Windows 8.1 upgrade that was also released on Thursday.
