Read out Windows 10 key and check licence key

With the release of Windows 10, many old practices have changed. Microsoft now sees a Operating system windows 10 is now more of a service, with numerous drastic updates in addition to many years of support. Part of this also affects the Windows 10 key, a licence key that no longer exists in the true sense of the word.

So what do you need for a new installation? And why are one-off licences such as for Windows 10 Home so practical 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 licence. This is accompanied by an individual hardware ID that takes into account the various configurations of your personal computer. This means that you do not need a licence key for a new installation on the same device. Microsoft has already saved all the necessary data.

At this point, a Windows 10 key almost seems like a relic from the long-forgotten days of Windows 7 or Windows 8.1 days. If you upgraded to Windows 10 for free back then, you can also continue to use the old licence key from the previous version. How you can read out this product key is explained in our detailed tutorial.

For Windows 10, the procedure is quite similar:

Checking the Windows 10 key with a special programme

Last but not least, there is of course, as always, a wealth of external software solutions, most of which are available free of charge. As a rule, you can remove the programme immediately after reading your licence key. You just have to expect some advertising.

At this point, we can recommend the Magical Jelly Bean Keyfinder recommended. According to its own information, the freeware can not only read your Windows 10 key, but also detect more than 300 product keys. You can then simply output your findings as a practical 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 you are using. Through a backdoor, you can quickly catch a pest or even just install an app that you don’t need. And then you have to use the AdwCleaner scan your entire PC again. So watch out!
