Product keys are essential in activating and verifying the authenticity of a software product. Windows product keys are no exception. Without a product key, you won’t be able to activate or access certain features of your copy of Windows. In this article, we’ll explore everything you need to know about Windows product keys.

What is a Windows product key?

A Windows product key is a unique alphanumeric code assigned to each licensed Windows copy. It is used to validate the authenticity of a copy of Windows and activate the software. Product keys come in different versions depending on the release of Windows and the purchase method – OEM (Original Equipment Manufacturer) or retail.

Where to find your Windows product key

There are two types of product keys that Windows uses – the digital product key and the traditional product key. The digital product key is embedded in the firmware of a computer with a Windows operating system. The traditional product key is usually found on the physical box or email receipt.

If you purchased a retail version of Windows, the product key will be included in the box containing the installation media. On the other hand, for a pre-built computer, the product key will most likely be embedded in the firmware. If you’re not sure where to find your Windows product key, you can visit the Microsoft website and follow their guide.

What happens when your Windows product key expires?

When a product key expires or is no longer valid, Windows will stop working or perform limited operations until the software is activated using a valid product key. You’ll see error messages and prompts reminding you to activate the software, but you won’t be able to use all features of your copy of Windows until you do.

How to activate Windows with a product key

If your copy of Windows needs activation, you can do it using a valid product key. This process can be done online or over the phone.

To activate your copy of Windows using an internet connection, go to Settings > Update and Security > Activation. Click on “Change product key” and enter the alphanumeric code as it appears on your activation key.

If you don’t have an internet connection, you can activate your copy of Windows over the phone by going to Settings > Update and Security > Activation. Select “Activate Windows” and then “Activate by phone.” Follow the instructions on the screen, and a customer support agent will help you activate your copy of Windows.
