How to Fix Windows Activation Error Server [2024 Guide]

Written By Farhan Max

I remember being prompted on Windows 10 to upgrade to Windows 11. I easily upgraded to Windows 11 and was having a decent time with it. Other than some minor complaints, Windows 11 is a great Operating System.

Sadly, the experience is not smooth for everyone. Many users are complaining about the Activation error, which does not allow them to activate Windows on their systems.

So, you might ask, why is the Activation Error occurring?

The Windows Activation error occurs because the user is using a copied version of Windows purchased by an organization. As the computers in an organization are usually activated through KMS licensing, which also can cause the Activation error to occur.

It is entirely natural for you to be frustrated with this issue, I can relate to that. Still, there is no reason for you to worry.

If you are looking for a fix to this problem, look no further as I have written the best methods in this post below.how-to-fix-windows-activation-error-server
