Majorly, the mass majority in the world uses Windows as it is affordable and comes in a variety of price ranges. The server which windows provide is specialized, and hence let us see how we can activate the server in our VPS and or other dedicated servers without having to shell out even a penny. We will be using the KMS client product key.

Activate windows server without product key

We are using KMS as it is free and can be activated for the end number of times. You will have to activate it every 180 days, which is decent considering you do not have to pay for it. Just easily renew it whenever you run out of license validity. Also, the license will be renewed on its own within the span of every 7 days, so you really do not even have to do anything.

NOTE: This method is not for standard users of the desktop edition of Windows, so do not continue, if you are. We do not hold any responsibility for any sort of damage if you do not listen to the warning.

Once that is out of the way, this method is supported by the following products:
Windows Server 2019/2016, 1803,1809, 1709, as well as 2008/2012 (R2).

We will be looking into two methods,

Method 1:

The first method is where you will install the client key of KMS manually, which will activate the Windows server.
