Besides, I have no problem at all with freeware developers trying to recoup a little money for their efforts: However, considering it would be run very rarely, not a major issue. NOTE: This one does include a rather irritating habit of requesting a $1 donation each and every time it’s closed out. Windows Product Key Viewer extracted the Windows 10 product key only but adds a little more information.

SterJo not only successfully extracted my Windows 10 product key but also the license key for my installed Microsoft office 2010: To save me repeating myself, in all cases simply run the software’s executable and each will automatically display its results which can then be saved to a simple text file.

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.
