However, I did retest six key finders which claim to extract Windows 10 product keys and, I’m happy to report, they all worked perfectly, with all six reporting the exact same product key.Īll these key finders are free and portable and work in a very similar fashion. Quite a few of these product key finders remain restricted to Windows 7 and before, retaining the old system of extracting license keys from the Registry, so still don’t work with Windows 10. Just after Windows 10 was first released, I tested a number of well known, free product key finders to see if they could successfully identify my Windows 10 product key and they all reported entirely different key numbers, proving to me that they had obviously not been updated to support the new system.

From Windows 8 and upward, however, Microsoft changed the system and, instead of embedding the product key in the registry, embedded it in BIOS/UEFI, making it more difficult to extract. In all operating systems prior to Windows 8, Microsoft embedded the product key in the Registry, which made it pretty simple for dedicated key finder software to identify and extract product key details.
