Unlike OEM keys, Digital licenses do not bind to the motherboard. This allows you to freely upgrade or change your operating system in the future and reinstall Windows even after a significant hardware change. The downside is that you will have to re-enter your product key every time you reinstall Windows. If you have forgotten your product key, you can simply sign in with the Microsoft account where the product key is bound to activate Windows. In the worst-case scenario that you did not bind the product key to a Microsoft account and you forgot your product key, simply use the Reset This PC feature to reinstall or reformat your PC without having to re-enter the product key.
