What is a Windows Product Key?
A Windows product key is made up of 25 letters and numbers. It is necessary to activate Windows and ensure that your Windows is legal.
A Windows 11 Pro product key might look like this:
XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
However, a product key is not the only way to activate your Windows 11. You can also use a digital license to activate your Windows.
A digital license will record the hardware of your computer and connect it with your Microsoft account. It doesn’t require the 25-character code like the product key.
Instead, it uses an internet connection and you must have a Microsoft account if you want to activate Windows using a digital license.
You will get a digital license when you upgrade your Windows and purchase Windows from the Microsoft Store app.
Can you install Windows 11 Pro without inserting the product key?
It is possible to install Windows 11 Pro on your PC without inserting the product key, but you won’t be able to use all features on Windows.
Besides, there will be a watermark in the bottom right corner saying, “Activate Windows. Go to Settings to activate Windows.”

Hence, in this post, we’ll show you where to find your Windows 11 Pro product key to activate your Windows.
Let’s get started!
