Windows 10 Product Key Viewer | Read Windows 10 License Key From UEFI Easily!

Life was much easier in the times of Windows 95/98 and 2000 as you had to enter the license key only during the installation and you had an operating system set up for life. But starting with Windows XP, Microsoft introduced activation that had to be done through the internet or over the telephone. And now that all the modern computers have UEFI instead of the traditional BIOS, the Windows 10 product key (license key or CD key) is stored directly in the UEFI memory – especially for the OEM devices such as laptops that come with Windows already installed. If you want to format the hard drive and reinstall Windows, Windows setup reads this key from the UEFI during the installation and proceeds to activation. Things have certainly become very complicated with time.

But how would you find out this Windows product key stored in the UEFI memory? This can be done from within Windows either using a PowerShell script or through a special tool Windows 10 Product Key Viewer. This tool can read your Windows 10 license key from UEFI or from registry, it can read the activation status and can also be used to backup or restore the activation status.


When you launch Windows 10 Product Key Viewer it launches a URL in your web browser. It does the same thing when you close it. This can be annoying for some people, but you agree to this behaviour in the program’s EULA which is stored in the same ZIP file as the program itself.

In the small window, Windows 10 Product Key Viewer displays the Windows 10 product key and allows you to copy it to the clipboard. It has two checkboxes, one is for backing up activation and another is for restoring the activation. The activation files are stored in the store sub-folder in the same folder as pkeyuibx.exe . It is useful if you reinstall Windows 10 on your PC – you can use this tool to restore the Windows activation instead of performing activation through Microsoft all over again.


Under the “System Info” tab of the program, you can see more information about the activation status. It displays the Windows version and edition, it displays the activation status (whether Windows 10 is activated or not), it displays activation channel (OEM, Retail, Volume License etc) and the channel ID.


This little tool can be of immense help when you have to reinstall Windows in your laptop and when you cannot find the Windows license key label on your computer. You can use it to read the license key, backup and restore the activation in seconds.

Hello :slightly_smiling_face:

First post don’t want to be rude or get involved with the virus or not discussion just want to present an alternative.

This will also display original product key.

CMD (Elevated)
wmic path softwarelicensingservice get OA3xOriginalProductKey

powershell “(Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey”

Tip: If you happen to be sysadmin in a organisation using volume licensing there is no need for the original keys so make sure you don’t get fired, extract the keys and sell them for a bargain :slight_smile:

We know some of the crack is a fake file to crash you computer or stealing some private information, but most of them is able to making the software running in full version and the virus alert is false positive.

This kinda tools are detected as malware or viruses because, by definition, they are. Their specific purpose is to modify programs and files so that they don’t work as designed. They delete verification files, modify registration status and do whatever they can to make their target not work as intended.

Try to run the software in sandbox and or use some online service like FireAMP 10 to analyze what file, registry are created but usually there is nothing suspicious.
