The Windows Product key acts as the unique key allotted to every device operating on the Windows OS that is proof that your Windows is original and bought from a trusted reseller, vendor, or manufacturer.

Without the Windows Product Key / Activation Key, you’ll not be able to use many Windows features and software on your device that you’ll find by the end of this article.

Let’s breakdown the methods to find Windows 11 product key that we’re going to cover in this article:


A product key, also known as an activation key, software key, application key, OEM key is a unique code that is linked to your Windows operating system and includes a specific set of 25 alphanumeric characters that is used to activate the software, hardware, or other products such as Ms 365 Applications. The first five characters identify the vendor who created the software.

The product key attests to the fact that the program’s copy of Windows is genuine and purchased from a verified source.

OEM/Retail keys and volume license keys are the two sorts of keys. Retail keys are purchased one at a time, one for each computer. Volume licensing keys, on the other hand, are purchased in bulk using business funds and distributed to all employees for utilization on their shared Workstations. Because the cost is shared over multiple users, volume licensing keys are usually less expensive than retail licenses, but each user must have their own product key to install it on their computer.


If you’ve purchased the Windows from a reseller or an online marketplace, you would’ve received it inside a package, check for the activation key in the manual included in the packaging.

If your Windows is pre-installed with the device, then, in most cases, you’ll find it at the backside of your laptop embedded inside a sticker, as in the image below.
