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?

 

Need help with transferring Windows 10 to new PC

*Nevermind I figured it out. I just bought a license key for $29.00. Thx though.
So my friend asked me to build him a new computer for work. The last one I built him was during the windows 7-10 upgrade grace period. I used to load windows 7, use windows loader to put in a product key, activate it, then upgrade to windows 10. Now that the grace period is over, and I'm working with new hardware, I was wondering if it is possible to install windows 10 from an already functioning computer that operated on a sata SSD to a new computer with an m.2 nvme SSD, using just the product key from the current windows 10 off of his computer. I use a program that grabs the product key called ProduKey.
Should I do a fresh install of windows 10 using his key after deactivating it from his current PC , instead of cloning drives correct? It would be nice not to have to pay microsoft $200 for windows 10 if he already has it and plans on not using his old pc anymore.

 

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.
