Windows 10: Different Product Keys

I am trying to determine the product key for system incase I need to reinstall windows. I have a windows 10 install along with a product key I used to activate windows. However when I run this command in powershell "wmic path SoftwareLicensingService get OA3xOriginalProductKey" I get a different product key. Which of these keys is the correct product keys is the correct key I should record?

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.

Any clues as to why he PKs do not match?

Also, planning to install Windows 10 Home, and wondering which of these Product IDs it will affect when it digitally signs the install.

Thank you!
