Can I Transfer an OEM Product Key to New PC?


I built a new PC and want to install windows 8.1. For this I need to buy a product key. I was told that OEM product keys are "married" to the motherboard for life.

But lets say I install win 8.1 and use an OEM product key yo activate it. And lets say in the future I get rid of the old motherboard and install a new motherboard. Will I be able to transfer the product key to the new motherboard? Or would I need a retail product key to transfer the key to a new PC or motherboard?

 

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.

 

Built New PC Windows 10 Activation Failed

I recently built a new PC, complete overhaul. I was using my friends PC it came with windows 8.1 Pro, I did the free upgrade to windows 10 pro it was activated as a digital license. When I built this new PC and selected I made a hardware change recently,
clicked my device and it says Windows was unable to activate at this time. I will list all of the solutions I tried.

-Old PC deactivate windows key through cmd prompt, New pc Activation failed.

-Showkey Plus and other key programs to unveil the key is giving me the generic Windows 10 pro key, doesn't Work.

-I don't know how to uncover the original Windows 8.1 key after upgrading it to Windows 10 pro. My friend that gave me the computer purchased a genuine version of windows 8.1 but he is unable to find the product key.

- I have tried all of the CMD prompt options slmgr / ect.. to try and find the original key, I'm unable to roll back to windows 8 to test that method on the old PC because it's past 30 days for the roll back.

- Microsoft support phone number was absolutely horrendous, I tried multiple times to fix this issue and the service rep is unable to even speak English or help me out in any way. I read online that support can fix this problem but I have yet to see any
possible way for that to happen.

I have a few possible fixes/questions, if I hooked up my old HDD from the other computer and put it into my new one could this possibly fix my issue? If I try and hook the old computer back up with my new SDD and try and clone windows 10 pro onto the SSD
from the HDD is that a possible fix?

thanks for the help I am really trying to get to the bottom of this as I don't want to pay 100$+ for windows when I have a genuine version of it sitting here in my old computer.
