How to Find your Windows 10 Product Key: Check your License!

How to find your Windows 10 product key? With the release of the latest version, many old best practices have changed. Now Microsoft understands an operating system more like a service, with many drastic updates in addition to years of support. Part of this also affects the Windows 10 key, a license key that doesn’t really exist anymore.

So what do you need for a new installation? And why are one-time licenses such as for Windows 10 Home so handy for this very reason? An overview.

Where is the Windows 10 Key stored?

The authenticity of your Windows 10 version is confirmed by a so-called digital license. This is accompanied by an individual hardware ID, which takes into account various configurations of your personal computer. This means that you do not need a license key for a new installation on the same device. Microsoft has already stored all the necessary data, and you just need to know how to find your Windows 10 product key.

  2. Confirm that you want to make changes to your computer.
  3. Copy the following into the input line: (Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey

Check the Windows 10 Key with a Special Program

Last but not least, there is of course a wealth of external software solutions, most of which are available for free. Usually, you can remove the program right after reading your license key. You just have to expect some advertising.

At this point, we can recommend the Magical Jelly Bean Keyfinder. According to its own information, the freeware can not only read your Windows 10 key, but also detect more than 300 product keys. Afterwards, you can simply output your findings as a handy text file or in CSV format.

As always, you should be careful when using such free programs, even if you have a modern virus protection. Through a backdoor, you can quickly catch malware or just install an app that you don’t need. You would have to scan your entire PC again with programs like AdwCleaner. So watch out if you want to learn how to find your Windows 10 product key.
