One month ago today, Microsoft
released the RTM versions of Windows 8.1 Enterprise for MSDN and TechNet subscribers to
download and use. Today, in conjunction
with the Windows 8.1 GA launch, Microsoft has also released ISO builds for both the 32-bit and 64-bit versions of the Windows 8.1 Enterprise SKU.
The
download page for the ISO builds state that businesses can install and use these versions of Windows 8.1 Enterprise for free for 90 days. While it's been made mostly for use by IT managers, there's no stopping anyone else from downloading and using these trial versions. However, Microsoft does offer a bit of a warning, saying:
This is evaluation
software designed for IT professionals interested in trying Windows 8.1 Enterprise on behalf of their organization. We do not recommend that you install this evaluation if you are not an IT professional or not professionally managing corporate networks.
