Windows 10: Cant activate Windows after changing PC

I know I have MS account registered for my license. I been using it for a years now and It works really fine. Today, I decided to change PC and as far as I remember I can migrate my license since it is connected to my MS Account but I cant activate Windows. I tried to run troubleshooter but it provides error.

windows activation—hardware changed siginficantly

From time to time on my thoroughbred PC, I get a Windows activation message that says my hardware changed siginificantly and I have to re-activate Windows. My hardware hasn't changed any more than a network card (went from a wireless g card to onboard lan to a wired network card), and the install is legit. Why is it doing this, and how can I stop it?

 

Windows 10 Activation after hardware change

Hi,



Thank you for writing to Microsoft Community Forums.



We understand the difficulties you are facing with the Windows 10 activation after a motherboard change. Ideally, if you have signed in with the same Microsoft account before
the changes made, then as per digital licensing policy Windows 10 PC gets activated after running the activation troubleshooter.



In order to get clarity and to assist you accordingly, please reply with the answers to the questions below:

• Did you upgrade the PC to Windows 10 or it came preinstalled with Windows 10?

• 
  Do you have the Product key?
  

Meanwhile, we would suggest you to refer the steps as mentioned in this article:
