UnknowingFool writes "After reports of update problems including bricking of some devices, Microsoft has pulled the 8.1 update for RT from their store while they investigate. '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.' While update problems are not new to software, could this be a consequence of Microsoft not releasing 8.1 RTM to developers? Developers may have experienced problems earlier and alerted Microsoft before it went live."
