This tutorial will show you how to change the current product key to a different product key to automatically activate your Windows 10 with instead. If Windows 10 wasn't pre-installed on your PC when purchased, and you used a product key to upgrade to Windows 10, then you'll need that same product key after the hardware change.

Hi Gen,
Microsoft has not released any product key for Windows 10. The key which you are referring to is a generic key which is usually seen when we skip the activation process or we do a key less installation. The activation for upgrade installation works this way, if you upgrade from an already activated Windows 8.1 or Windows 7 SP 1 PC your PC's activation will carry forward which means it will be in an activated state after the upgrade to Windows 10. If you perform a clean install of Windows 10 you have to purchase a product key or you can go back to Windows 8, upgrade to Windows 8.1 install the required updates and you can upgrade to Windows 10.

I didn't upgrade from an already activated Windows 8.1 but I upgraded from an already activated windows 8 using Media Creation Tool. And when I did that, MCT didn't ask me for Product key. Is that ok?

I've tried to upgrade to windows 10 from windows 8.1 using Windows Update.
It's exactly the same, the product key changed to BT79Q-G7N6G-PGBYW-4YWX6-6F4BT
When I type slmgr.vbs /dli in CMD, it says my windows is Retail, I think it should be OEM like in Windows 8.1.
