One thing that we’ve made clear over the last few months, beginning with TechEd North America, TechEd Europe, WPC and in conversations with customers: Windows 8.1 is designed with businesses in mind. Windows 8.1 Enterprise RTM comes with a host of new capabilities only available in the Enterprise edition, as well as new industry-leading security features.
Beginning today, TechNet and MSDN subscribers will now have access to Windows 8.1 Enterprise RTM. This also includes access for Volume License (VL) customers with an active Software Assurance (SA) agreement, as you receive a TechNet subscription as part of SA.
Still happy with my MS TechNet subscription for MCT's! :)
