How to unlink a product key from the Microsoft account?

It is dead easy to remove the digital link from MS account. Simply change login to a local licence.

Then use your product key on new pc. If Windows complains key has already been used, use telephone activation and at step where it asks about licence, state it will only be used on new pc.

It looks like you defininately need to link a microsoft account with windows 10 or it says go to the next section (if u didn't) and the next section explains how to purchase a new licence:
"

• Select I changed hardware on this device recently, then select Next.
  
• Enter your connected Microsoft account and password, then select Sign in. The troubleshooter will only work with the connected Microsoft account.
  
• From the list of devices that are linked to your Microsoft account, select the check box next to This is the device I’m using right now.
  
• Select Activate.

If you don’t see the device you’re using in the list of results, make sure that you signed in using the same Microsoft account you associated with the Windows 10 digital license on your device.
If you continue to experience errors while activating, see Get help with Windows activation errors and locate the error you're getting.
If you didn’t link your Microsoft account to the digital license before the hardware change AND you used a product key to upgrade to Windows 10, then continue to next section."
