Update: The Enterprise version of Windows 8.1 is also available on TechNet and MSDN.
Today Brandon LeBlanc announced the RTM availability of Windows 8.1, Windows 8.1 Pro and Windows Server 2012 R2 on TechNet and MSDN.
Windows 8.1 Enterprise version will follow somewhere in the upcoming weeks.
I’ve already started the upgrade process of my home lab with the upgrade of both my domain controllers to Windows Server 2012 R2. What about you?
