Windows 10: Use product key with a different account

Hello,I need to reinstall Windows 10 on my computer and was wondering if I could take this chance to change which Microsoft account is associated to my product key. It is currently linked to an old Hotmail account that I don't really use anymore, and would like to use my newer Outlook one instead. Is there a way to do so?

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.

 

Different Product Keys?

Have an Acer with a COA showing the product key for Windows 7.
Use this one for activation.
Ran Belarc Advisor, and it shows a different Product key for Windows 7.
All Acer's with 7 home have that same factory key.
