Windows 10: MY OEM KEY NOT WORKING

I upgrade my laptop windows in 11 home to pro in last month,but OEM key not working.

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).

 

Windows 7 OEM key

Perhaps the OEM key has been used a few times already and cannot be used again.
I have changed motherboards in laptops and the OEM key worked, without having to call Microsoft.
