Windows 10: Windows 8.1 ENG INTL FOR OEM SOFTWARE Product key not working after clean install of Windows 10

Hello,I just upgraded my CPU and did a clean install of Windows 10 Home via media creation tool/USB but when I tried to activate with my Windows 8.1 ENG INTL FOR OEM SOFTWARE Product key, it doesn't work and gives me the following:We can't activate windows on this device because you don't have a valid digital license or product key 0x803fa067Before my upgrade, I had an active Windows 10. I read that OEM is only for one PC but I upgraded this same PC 4-5 years ago, clean installed Windows 10 and also used this product key with success. Why now is it not allow it to activate?Has something chan

Question On OEM Windows clean install......

"Flavors" of Windows licenses

Windows can be a little "odd" about license keys. There are at least 4 categories:

• Retail
• OEM
• Volume (electronic download)
• Corporate (no key needed)

For guaranteed success, the license key and media should be in the same category. If you have retail media, you may not be able to install it using an OEM or Volume license key, even though the key is valid for that version of Windows. *Wtf :wtf: Apparently, this is part of Microsoft's anti-piracy scheme (i.e., all customers are guilty until proven innocent).
