Windows 10 Key transferring help?

[LampGoat]

I got some new parts recently to upgrade my computer (just motherboard, CPU, and gpu) and this is the first time I'm doing this. Hardware-wise I'm okay, I can plug in everything but I'm not sure what to do after that. I already Windows 10 (computer originally came with Windows 8 but I got the free upgrade) and I'd like to transfer the key to the new motherboard. How would I go about doing that?
By the way the computer's specs can be found here:

Before you change out your motherboard you need to link your Windows to your Microsoft account. It is very important that you do this before you change out your motherboard.

After you link your Windows to your Microsoft account then you can go ahead and change out your motherboard and CPU and then do a clean install because you will need new drivers.

you need to tell what kind of license you have ?

If you have a digital license that is associated to your microsoft account , then there is no issue . Do the hardware change and re-login with your account .
But if it's not a digital one , then you gotta link your license to your account via the activation page .

Exactly what arunvasu said. You have to determine whether or not you already had a digital license or not. My post "ASSUMED" that you did not have a digital license yet, but as arunvasu indicated, you may very well have a digital license already. If you do, then you are good to go and you have to do is link up your new equipment to your license.
