Product key association disable on old pc

Hey,


I sold my old pc to a friend. He installed some missing parts (HDD, GPU and RAM). Then we installed Windows 10 Home 64-bit version from USB stick. I was surprised to see that windows was automatically activated after that. I did some digging and found out that it is using my product key, which i use now in my own new pc. My friend does not have his own product key, the idea was that he just uses the unactivated windows with limited features.


I uninstalled my Windows 10 product key via command prompt in friends computer (as i understand this is only local solution, if he reinstall windows or clicks the active button, it reactivates automatically with my product key) and now it says windows is not activated, but my product key is still shown with Produkey app in his pc. So far windows is still activated my own pc.


My questions:

1. Is this all i need to do?
2. How do i get rid of product key showing still with product key showing apps on my friend's computer?
3. Is there a way to get rid of association of my product key on that old pc that i sold to friend?

EDIT: I originally installed windows 10 via upgrade option from Windows 7, if that matters.

 

Installing Windows 10 on New PC?

I'm going to be building a new PC on Christmas and want to install Windows 10 on it. I have Windows 10 on my current PC, which I installed upgrading from 8.1 with the files on a USB. How do I go about installing a clean copy of Windows 10 on this new PC? I think I recall something about installing it once makes Microsoft recognize your hardware, but since this will be a PC I'm not sure what steps I need to take. Do I need to go 8.1 -> 10 or is there a method of going directly to 10?

 

Installing Win 10 Pro on new HD (original PC) keeps asking for product key

In 2013, I installed Windows 8 Pro with a valid product key. That was upgraded to Windows 8.1, and that was upgraded to Windows 10.

My hard drive crashed and I am reinstalling Windows 10 Pro from a USB drive created with the Media Creation Tool. When asked to save files, I chose to perform a new install, since the hard driver was empty.

Now it asks for a product key. I have a key for Windows 8 and Windows 8.1, but I do not have a product key for Windows 10.

The installer won't the installer accept the old 8/8.1 keys.

How can I reinstall Windows 10 Pro on this PC without buying a new license?

Thanks.
