Windows 10: Using Windows 10 free upgrade from Windows 7 licence on a new computer?

Hi, I have an old computer in which it was updated to Windows 10 from Windows 7. It was using a digital licence, but I retrieved the full serial key by using "Nirsoft ProduKey".

I used the command "slmgr /dlv" to find if my licence was RETAIL, and it is, here is the pic showing it.



Also the partial product key matches with my full key extracted using Produkey from Nirsoft.

What I did was to execute the commands "slmgr /upk" and "slmgr /cpky" to delete the key from this computer so I can use it on my new machine.

Windows became unlicensed in the old machine and I proceed to uninstall it.

The problem comes when I try to activate the new computer while I'm installing Windows, the installer gladly accepts the extracted serial key and installs the corresponding Windows 10 edition, but when I'm using the OS it says that the key is not really valid and doesn't activate.

I must say that the licence it's not linked to any Microsoft account since I always used a local account in the old computer and Windows it's not installed there anymore.

What can I do?



Thanks in advance!

I thought I made it idiot-proof by adding that sidenote in the brackets. I was wrong.

-> If you upgrade to Windows 10 from Windows 8.1/7 within the first year of Windows 10's launch, you can have it for free till the Sun runs out of hydrogen. You get an upgrade key, and you can use that even if you need to reinstall things 3 years later.

-> If you're trying to upgrade to Windows 10 from Windows 8.1/7 after 1 year following Windows 10 launch, you pay for the upgrade.
