If you lost your Windows license key, you can still recover it from the computer or device on which it’s installed. What’s the easiest and fastest way of finding your Windows product key? The answer is to use a desktop app that can search for and display the Windows product key. The problem is that there are many programs of this type on the Internet and not all of them are good. That’s why we decided to test a few of them and identify those that work best for all modern versions of Windows: Windows 7, Windows 8.1 and Windows 10. You never know when you need to recover your lost license key so let’s get started with our comparison:
1. Recover your Windows product key with Belarc Advisor
Belarc Advisor is a free program that you download and install on your computer. It doesn’t just show your Windows license key but it also builds a detailed profile of your installed software and hardware, network inventory, missing Microsoft hotfixes, antivirus status and security benchmarks.
When you run it, it spends quite a while analyzing the local network of your computer or device.
When done, the results are shown in a local web page. It displays a lot of information and you might feel lost at first.
If you look carefully, you’ll find a link called Software Licenses on the left, which takes you to the section with the same name. There you will find several software licenses, including the one for your Windows installation.
2. Recover your Windows product key with Magical Jelly Bean Keyfinder
Magical Jelly Bean Keyfinder has a very weird name but it is a free program and it works. When installing it, pay attention though, as it also tries to install some web browser extensions that will display ads and “shopping offers”. You will probably not want that on your computer.
Magical Jelly Bean Keyfinder has a very simple interface and it displays your Windows product in just a couple of seconds.
3. Recover your Windows product key with ProduKey
ProduKey is a small utility that you can use as a portable app or, if you prefer, you can install it. If you choose to use the portable version, you will download a ZIP archive. Then, extract it and run ProduKey.exe.
The program launches and displays your Windows product key in an instant. This desktop app is small, free, fast and easy to use. Highly recommended!
4. Recover your Windows product key with SterJo Key Finder
SterJo Key Finder is another small program that’s available both as a portable app or as a regular installer. If you choose the portable variant, you will get a small zip archive which you must extract. Then, run the KeyFinder.exe executable.
SterJo Key Finder launches fast and displays your Windows product key in an instant. We like this desktop app: it’s portable, free and fast.
5. Recover your Windows product key with ShowKeyPlus
ShowKeyPlus is a very simple portable application. You download it as a zip file, extract it and run the ShowKeyPlus.exe. This app displays your Windows product key instantly and it’s ad-free. It’s worth noting that ShowKeyPlus can also find the product key stored inside a Windows backup.
6. Recover your Windows product key with Free PC Audit
Free PC Audit is a free portable tool that you simply download and run. It’s designed to extract details about the hardware components of your PC as well as the software apps installed and their product keys. This information includes the product key of your Windows installation.
It’s small and ad-free but it’s slow at displaying the your product key because it analyzes other things too. If you’re not searching just for your Windows license key, but also other details about your computer, this is a good app and we recommend using it.
