Recover Windows 10 key from Windows 7/8 / 8.1

And what happens if we change the hardware?

As we have seen, Microsoft has modified the activation of system licenses in Windows 10. Compared to the use of the classic alphanumeric series, Windows 10 connects to the company’s servers and activates the system on each specific computer, assigning it a “Digital license”. A simpler method, but what happens if we modify the hardware of the equipment?

In those cases of major hardware change (it usually only happens if we change the motherboard) we will lose that activation. But it has a solution in two ways:

If you have a digital license. You will need to add your Microsoft account first and link it to the device’s digital license. After linking your Microsoft account, run the activation troubleshooter to reactivate Windows 10.
If you don’t have a digital license. If Windows 10 didn’t come pre-installed on your device when you purchased it and you used a product key to upgrade to Windows 10, you’ll need that same product key after the hardware change.
