Windows 10: How to recover Windows 10 Product Key/Activation from old PC

I recently (a few months ago) decided I wanted to change some of the specs in my PC. Along with selling my old GPU, power supply, and case; I sold my 500GB SATA SSD in favor of a 1TB M.2 model. Before I made these changes and sold the parts, I was smart enough to wipe the ssd clean.


I was wondering if there is any way I can use my Microsoft account to restore my activation of windows and maybe access the product key? Any help on this confusing topic would be much appreciated.

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.

It's not "your" product key. It is the generic Windows 10 product key that everyone gets when they upgrade from Windows 7/8/8.1.

And, BTW, using Windows 10 unactivated with the limited features violates the End Users License Agreement:

Your friend that has the computer now should just enter the generic Windows 10 Home product key and let it activate from the digital license stored on Microsoft Activation Servers.
