Windows Product Key Finder

If you’ve misplaced your Windows product key number, or your computer’s COA label has been damaged, you can still retrieve the serial with the help of a third-party application, such as the one we’re reviewing today.

Windows Product Key Finder is a very simple utility that, true to its name, can help you retrieve the product key of your installed OS. It is a portable, open source program that works with Windows 10, 8.1, 8 and 7.

This application is about as simple as you could expect, and it is very easy to use. The only thing you need to do in order to retrieve your serial is double-click the downloaded executable file.

Once the product key has been displayed, you can select and copy it to the clipboard manually, but you can also click the “Copy key to clipboard” button to perform the same function.

One of the great things about this application is that there is no need to install anything on your PC before running it. It can be launched from any device, and you don’t have to worry about anything being left behind.

The fact that Windows Product Key Finder is an open-source application certainly helps, as you can check the source code yourself to see exactly how it extracts and handles product keys.

It is worth noting that, if you have upgraded to Windows 10 from Windows 8.1, 8 or 7, the OS will have a generic product key, which is no longer necessary even when performing a clean install.

Windows Product Key Finder is a no-frills utility that can recover your Windows serial if you can’t find it for whatever reason. It is portable, open-source and very easy to use.
