How to find your Windows 10 product key

Within the ‘About your PC’ section of the system control panel, details such as Device IDs and Product IDs are available, but conspicuously absent is information regarding your Windows product key.

Microsoft and its system partners ceased the practice of providing stickers or certificates displaying Windows product keys long ago. Subsequently, Windows activation relies on a digital license linked to your system’s hardware fingerprint.

While this approach simplifies the process of reinstalling, situations may arise where access to the product key is necessary. These can include an OS downgrade or various upgrade projects.

If you find yourself in possession of a PC with an activated copy of Windows 10 and a desire to retrieve the product key, a solution involving a few command prompt entries is both swift and straightforward. We’ve laid out the steps below so you can your Windows 10 product key without any hassle.
