If need to retrieve your operating system's product key for one reason or another, ShowKeyPlus is a free tool that comes in handy. The Windows product key viewer lets you retrieve the key from different locations, and you can even use it to get the key of an earlier installation after an upgrade.

Features and Functions

You only need to download and extract the executable file where you want. This is a portable application that runs directly from its installation folder. You should launch it with administrator privileges.

All it takes to display the product key(s) is to launch the application. The Windows product key viewer takes a few seconds to open a small window that immediately displays the installed key and other related details.

The details that you will see will depend on the originally installed operating system and any upgrade made. If you had upgraded your operating system, the application will not only display the product key of the upgraded edition but also that of the originally installed OEM.

If you had upgraded from Windows 8.1 to Windows 10, for example, the software will show you the edition and key of Windows 8.1 as well as installed key and product ID of Windows 10. You will also see the product name of the current operating system.

The software also gives you the opportunity to retrieve the product key from a backup. You simply need to browse for and select the backup file and the application will take care of the rest.

You can use a dedicated key to save the details in a text file for later reference.

Apart from checking your Windows product key, you can use the application to verify other product keys. You only need to enter a product key and the application will automatically check its validity, edition and compatibility with your operating system.


ShowKeyPlus is an intuitive Windows product key viewer that allows you to see and save keys of the current and any earlier operating system from which you upgraded. Since the application displays the keys automatically on its user interface, the feature to toggle masking may come in handy depending on the environment where you are using it.
