While sniffing around the registry in Windows 8, the guys at Windows 8 Beta seem to have stumbled upon what appear to be references to Windows 8 SKUs. Here’s the list of every SKU — a total of nine — that was in the registry file:
- Windows 8 Enterprise Edition
- Windows 8 Enterprise Eval edition
- Windows 8 Home Basic Edition
- Windows 8 Home Premium edition
- Windows 8 ARM edition
- Windows 8 Professional edition
- Windows 8 Professional Plus edition
- Windows 8 Starter edition
- Windows 8 Ultimate edition
As you can see, compared to Windows 7, there are two additional SKUs that are mentioned: Windows 8 ARM edition (which we knew would exist), and, interestingly enough, a Professional Plus edition SKU. There are also what appear to be placeholder “pre-release” SKUs that are in the list, pictured above (though this entire list could possibly be inaccurate placeholder content).
Below is a screenshot that Windows 8 Beta took of this very registry file, but in Windows 7.
Should this list prove to be correct, I cannot think of any reasons as to why there needs to be a Professional Plus SKU; if anything, Microsoft should work towards simplifying their editions of Windows 8 instead of adding to their abundance. But again, it is also likely that this content is inaccurate. An obscure registry key in a pre-release version of Windows is hardly confirmation of anything, so this one should be taken with a grain of salt. If you have an additional grain of salt at hand, let me point out a similar list of alleged SKUs that recently cropped up that is likely also placeholder content.
