Is this license official ?

Hey hlavva,

This is not a Microsoft authorized reseller. Some sell volume license keys meant to be used with multiple keys that can be invalidated at any time, and is not legal. Be careful of where you get your licenses or you'll risk facing problems down the line.

Hope this helps.

Hi hlavva,

No those are not legit licences, they are selling volume licence keys.

Those product keys may work for a month or so, if at all and will then expire.

You will be wasting your money if you purchase one of those licences

The best and probably only place to purchase Windows 10 is from the Microsoft Store . ..

Hi,
Microsoft warns at https://www.microsoft.com/en-us/howtotell/Shop....

Beware of Product Keys Sold Separately
With the exception of Product Key Cards (PKC’s) distributed with COA’s, Microsoft does not distribute products keys as standalone products. If you see a listing on an auction site, online classified ad, or other online page advertising product keys for sale, it’s a good indication that the keys are likely stolen or counterfeit. If you were to purchase and use a stolen or counterfeit product key to activate Windows installed on your PC, the key may not work for activation, may already be in use on another PC, or it might be blocked from use later by Microsoft when the key is reported stolen.

Only Amazon (not the marketplace section) and Microsoft itself are authorized to sell Digital downloads.

This site is likely reselling MSDN licenses.

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.

If you need to purchase a genuine license, do so from the Microsoft Store:
