I want to know the answer to the following question:
What exemption was removed from Windows 8.1?
All the background I'm provided with is that "With the retail release returning to full version software for Windows 8.1, the "Personal Use License" exemption was removed from the OEM SKU, meaning that end users building their own PCs for personal use must use the full retail version in order to satisfy the Windows 8.1 licensing requirements.". Is that enough to answer the question?
