Windows Server product key is a crucial digital key in the form of an arrangement of a total of 25 characters. It is of utmost importance as this key is used for the activation of Windows. Without this key, users may not be able to gain complete control of their Windows server. They may also not be able to use several Windows integrated programs that require the input of the Windows server key for activation. In this article, we'll be looking at some of the ways we can learn what our Windows server key is. So, without any further delay, let's begin.

Step 3. Scroll down, locate ProductId, right-click on it and select Modify. The number displayed is your Windows server product key. Avoid making any changes to it, and click on the Cancel button after you've noted it down somewhere.

The steps listed above were the correct guide on finding your Windows server product key in Registry. Let's now take a look at the other possible fixes we can try.

Fix 2. Using PowerShell to Find Windows Product Key
