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).

Downgrade Windows 10 OEM to Windows 7 Professional - Product Key

Hi Andre,

Thanks for your response. This is really the answer that I was looking for, at first I just couldn't understand why it was called a downgrade when there's a need to have another license, but your answer clarified it.

If your OEM has not injected your product key into the BIOS on your PC, follow these steps:

These statements defeat the purpose of downgrade rights. The workaround in this situation is to use an existing Windows 7 or Windows 8.1 Product Key to initiate the activation.
The tricky part of this is, it can be a product key that is already in use but corresponds with the edition. The burden is on you the user to find such a product key.

For the edition, customer is using a Windows 10 Pro OEM which gives downgrade rights to Windows 7 Professional. However, I don't think that I can download the image using the link
below as it needs a retail license (25 characters). I only have the 20 characters OEM product ID. Can you suggest where can I possibly download the Windows 7 Pro installer?

Thanks and Regards,
