Windows 10: Transfer Windows 10 Pro license from dead computer to current PC with Windows 10 Home

I had an old PC with a Windows 8.1 Retail License that was upgraded to Windows 10 Pro during the free upgrade window a few years ago. That computer stopped working and rather than spending money on repairing it, I bought a new computer that has Windows 10 Home pre-installed. Is it possible for me to transfer my previous Windows 10 Pro license to my new computer?


I tried Go to Settings>Update and security>Activation and run the troubleshooter as suggested in some forums but I don't even see a troubleshooter option, even when I logged in as Admin.


Thanks!

Windows 10 Hardware change

Technically, a new motherboard constitutes a new computer and if your current copy of Windows 10 was an upgrade from Windows 7 or Windows 8.1, you need to buy a new W10 license. While the process may allow you to activate Windows 10 that was an upgrade, that does not make it legal to do so.

The current free Windows 10 program is only for people who currently have a legal copy of Window 7 or Windows 8.1 installed on their systems. And those upgrade licenses are NOT legally transferable to new computers.

If you purchased a full retail W10 license separately for your current computer and wish to install this W10 on this new computer, you can legally do that as long as you uninstalled it from the old computer.

Windows system builder licensing for personal use

The good new is, once you buy a new Windows 10 license, you can transfer it to a new computer as many times as you like. So this would be a one time purchase.

 

Windows 10 upgrade license

The interesting question is that: the upgrade takes place before 29 of July. If I upgrade the PC (change the MB), and I transfer the Win 8.1 license to this new PC (cause 8.1 is retail FPP), will I be able to upgrade to Windows 10 for free? Or a upgrade license must be bought?

 

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.
