Find your Windows product key. 8 apps that help you recover it!
If you lost your Windows license key, you could recover it from the computer or device on which it is installed. You can do that with an app that can search for and display the Windows product key. The problem is that there are many apps 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 are completely free and which work best with all modern versions of Windows: Windows 10, Windows 7 and Windows 8.1. You never know when you need to recover your lost license key, so let's get started with our app comparison:
1. Find your Windows product key with Belarc Advisor
Belarc Advisor is a free program that you download and install on your PC. It doesn't just show your Windows license key, but it also builds a detailed profile of your software and hardware, network inventory, missing Microsoft hotfixes, antivirus status, and security benchmarks. After it analyzes your computer or device, it shows you the results in a local web page. Look carefully on the left side of the browser window, and you should find a link called Software Licenses: click or tap on it. It takes you to the Software Licenses page section, where it shows you the software licenses it identified, including the one for your Windows installation.

Magical Jelly Bean Keyfinder has a peculiar name but it is a free program, and it works well. Magical Jelly Bean Keyfinder has a simple user interface, and it displays your Windows product in just a couple of seconds.
3. Find 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 can get it as a ZIP archive.

4. Find your Windows product key with SterJo Key Finder

Just like its name points out, Winkeyfinder is an app that can find the serial key used by your Windows computer. It's a portable app which means that you do not have to install it.
