Windows 8.1 now available to MSDN and Technet Subscribers

Win8Blue_WebToday, in a change of heart, Microsoft has released the RTM Windows 8.1 bits to MSDN and TechNet subscribers.

In a blog post published by Steve Guggenheimer, Microsoft notes that they are working through how to best support developers and IT pros as they align to a faster release cadence.

In my opinion, it would have been much better to release the bits to developers and IT pros back around the original RTM timeframe, but this is better than nothing.

For the build curious amongst us, the build string for Windows 8.1 RTM is 9600.winblue_rtm.130821-1623. The SHA1 hashes for the ISO have been posted below along with steps to check the integrity of the downloaded ISO.

Hashes for today’s release:
