Then, use the following info to help you successfully prepare for a hardware change and reactivate Windows. To find out which you need, see 'What activation method do I use, product key or digital license?' in Activate Windows. To activate Windows, you'll need either a digital license or a product key. If you make significant hardware changes on your device, such as replacing your motherboard, Windows will no longer find a license that matches your device, and you’ll need to reactivate Windows to get it up and running.
