Earlier today, Microsoft announced that we are making the current RTM bits for Windows 8.1 and Windows Server 2012 R2 available to TechNet and MSDN subscribers effective immediately.
Visual Studio 2013 Release Candidate is also now available.
We heard your feedback that you needed the RTM bits now. We listened and are making the RTM bits available.
We will continue to validate the Windows Server 2012 R2 software with our partners, and there will be some additional updates to this build prior to GA in October.
I can’t wait to hear your feedback once you get started with the software!
