Volume License Key'd Windows 8 Pro Upgrade Assistance Need

Hi all, new user, first time poster and hoping you smart cats can help me. The forums have always provided answers in the past, but I feel I need to ask this one myself.

So, after three hours on the phone with MS Customer Support today (Worst time to call, by the way), I find out that this computer I purchased from a local company I did contract work for is unable to upgrade from Windows 8 to Windows 8.1, and therefore, unable to be upgraded to Windows 10. It has a volume license key, which is not allowed to be upgraded via store or any other method (apparently).

MS support suggested I take this back to the company I purchased it from. The issue with that is that I purchased it at very low cost because the company was going out of business. No luck there. I thought maybe it was an Enterprise copy, since those cannot be upgraded, but the System screen shows Windows 8 Pro.



So Microsoft's one and only suggestion was to purchase a "legitimate" product key, which got me to thinking it was a pirated version or some sort, but they checked and said it was not.

So, I come to you with the hopes that someone has successfully upgraded a volume license Windows 8 Pro to Windows 8.1, and then, hopefully, to Windows 10. I will leave this here and head off to bed, and I sincerely hope someone can be kind enough to assist. Please let me know if you need further information. Cheers!

Volume MAK keys are not only version, but edition specific, meaning one can't upgrade with them - thus going to 8.1, let alone Win 10, is not possible without a new key.

PS: Run ShowkeyPlus to check if you have a Windows 7 OEM marker - we can then get you back to factory install and upgrade to Win 10 from there.
