Don't worry, it's not the end of the world, and it doesn't necessarily mean you have to shell out for another license. If you've done things right and have one digital license linked to your accountRegaining access is a fairly simple process that only requires following a few specific steps for Microsoft to recognize that the PC is still yours.
How to verify the linking of your Microsoft account

Before you panic, the first thing to do is check if your license was properly linked to your profile. To do this, go to the Home menu and navigate to Settings, then Update & Security, and then ActivationThere you will see the current status of your system.
