Windows 10 reseller - legit or not

No, its not legitimate, the seller is likely reselling MSDN keys at a significant discount. Only Microsoft and Amazon.com are permitted to sell digital downloads of Windows 10. Avoid it.

Here is how you can still get Windows 10 fore free:

About MSDN or TechNet Product Keys

They are genuine Microsoft product keys, they are actually retail licenses, but it is intended for a particular product channel either the Microsoft Software Developer Network (MSDN) or TechNet for IT Professionals who pay a subscription fee. The main purpose is for evaluation purposes. The great thing about them, unlike trial Microsoft software, MSDN or TechNet keys don't expire. Because the agreement under which the subscription is provided is a single license, none of the software should be distributed outside of it. Even though its $50,000 worth of licenses, it is for one person only to use and no one else. Unfortunately, regardless of the licensing terms, persons still abuse the program, either giveaway product keys or resell it on auction sites. Microsoft licenses it in good faith that customers won't do so, but I guess human nature wins out.

In your case, what probably happened is, you bought an MSDN licensed key, which carries up to 10 activations unlike full packaged retail licenses which only carry 1 activation. The person who sold it to you probably sold it to 10 other persons. Somewhere along the way, one of those persons might have installed it on a second system, activated it, because it went past 10 activation threshold, Microsoft detected it that it was being abused and blocked the key from further use.

Hi

Can you check this too:

FWIW even if I go to genuine retailers to look at the prices for Office or Windows, I'm seeing the price is almost HALF of what the price is quoted as on the Microsoft Store. For example, £220 for a MS product that I can buy from a trusted retailer for £140.

We are volunteers willing to help you try to resolve this issue.

Compare prices to the Microsoft Store.

When you see heavily discounted prices like that a red flag should go up those are not legitimate licenses. Likely they will work for a short while until Microsoft realizes they are selling the same license over and over and stops it.
