Windows 10: retail product key

i like to if the product key sold by Bestbuy store is legit or a scam

:)

 

Extract the Windows 10 retail product key

I tried to find the retail product key of Windows 10 with software like Nirsoft's ProduKey and Belarc Advisor. But the code they show doesn't match the code written on the official paper.

How do I get the right product key out of Windows?

 

Using the current device's product key on my another device.

On old PC:
Uninstall retail product key:

1. Disable secure boot(if turned on in BIOS)
2. Boot into Windows
3. Enter slmgr /upk and wait for this to complete. This will uninstall the current product key from Windows and put it into an unlicensed state.
4. Enter slmgr /cpky and wait for this to complete. This will remove the product key from the registry if it's still there.
5. Restart
6. Wait a little while and then use the retail key on the new machine.
7. Set up secure boot(recommended)

Your old machine should go back to home, or you might need to do a clean install, I'm not sure there.
