Windows 10: Windows 10 Retail License Key not Working

I just built a new pc. My old laptop has the retail version of Windows 10, and I understand that it means that I can transfer my license to the new PC. I uninstalled and deactivated the license on my old laptop, but when I entered the 25 digit key on my new PC, it said that it can't be used on this version of windows. Please help! I don't want to buy a whole new license if there is a solution. Thanks so much.

I read through most of that thread and it seems you have to jump through windows insider hoops. Is there a Retail Windows 10 x64 PRO ISO I can download directly from microsoft that my windows 8 key will work with?

 

Windows 10 upgrade license

Hello guys,

I have 1 license of WIndows 8.1 FPP/retail license. I want to upgrade to WIndows 10, but I one thing is unclear to me.
If I upgrade, will WIndows 10 license be retail or it will "turn" into some sort of OEM license?

I ask this because I upgrade my PC, you know, more memory, replace HDD, and I intend to upgrade the MB and CPU to Kaby Lake platform sometime in the future, (and of course sell the replaced hardware)
This thing is not clearly mentioned anywhere.

Thank you.

 

Windows 10 retail license key

As noted, only Microsoft and through special relations and partnership, Amazon.com can resell digital licenses.

Those listed on ebay are likely MSDN product keys.

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.
