6 Free apps for recovering your lost Windows product key

Windows Phone Lumia 520

Important information regarding software, services, and online accounts is best kept in a password manager, but in real life, we hardly experience an ideal scenario. If you forgot or lost your Windows license key, this information is still stored on your machine and more importantly, it can be recovered.

There’s no shortage of applications that can help you get back your Windows product key, but only a few of them are actually reliable. For this reason, we’ve selected a few that are actually worth your while, so continue reading to find out more details.



Nir Sofer is a prolific software developer and he has a great collection of Windows utilities (you can see them all on his website). He also created ProduKey, a lightweight and optionally portable tool which does one thing, but it works extremely well.

As soon as you open the app, it will show all Windows OS software keys present on your machine as well as license keys for Microsoft Office and SQL Server if these applications are installed on your computer. It really couldn’t get any easier.

SterJo Key Finder

You can use SterJo Key Finder to recover license keys for Windows OS and Windows software as well as other apps you may have on your computer. This app also works very fast – all you have to do is open it. The detected license keys will be displayed as a list in the plain and functional interface.



ShowKeyPlus is also a straightforward product key recovery tool, and it’s also portable. After you download the archive, extract its contents and run the executable.

Then, in the app’s interface, you’ll see your Windows product key along with other related details like the product ID and OEM key (if any). A particularly interesting capability of the app is it can also detect product keys contained by Windows backups.

Magical Jelly Bean Keyfinder

Despite the odd naming decision, Magical Jelly Bean Keyfinder will do the job as far as product key recovery is considered. However, I recommend you install it with caution as it attempts to push third-party browser extensions on your system. You can opt out as long as you pay attention during the setup.

Nevertheless, Magical Jelly Bean Keyfinder will detect your Windows license key and the same information can be retrieved from Office 2010.

Free PC Audit

Free PC Audit is a portable utility so all you need to do is run it – no setup required. While it can do much more than simply retrieve your OS product key, it works very well for this purpose.

Should you be interested to see all the hardware information of your computer, Free PC Audit provides this functionality as well so you can use it in more ways than one.

Belarc Advisor

Belarc Advisor

Belarc Advisor is a free software utility designed to offer you complete information on your computer’s hardware and installed applications. The analysis process that initiates when you run the tool may take a while, in order to retrieve all these details but among them, you will also find your Windows product key in the “Software licenses” section.
