How to Clear Product Key From The Registry in Windows 10

Windows 10 saves your product key to the registry. You may have heard of, and possibly used some apps that allow you to look up your Windows 10 product key. These apps make use of the information stored in the registry to find and display the product key. If you ever need to, you can delete a product key from the registry.

    Note
Deleting the key will not impact your current activation status.


You will need administrative rights to delete a product key from Windows 10.
