Activate Windows with KMS server


If you’ve  installed Windows with a MAK key and now want to change it to KMS or installed OS (never activated), and need to activate WIndows with KMS server, this article will definitely help you.

Activate Windows with KMS Server

Step 1: KMS Client Setup Key

You must change the product activation key to the public KMS Client Setup Key. For each version of Windows, this key is unique.

Run Command prompt with elevated privileges on the machine you are wanting to activate and type:

slmgr.vbs /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

(XXXXX is KMS for your Windows version key from the table below)

For example, we want to activate Windows Server 2012 R2 using KMS. The KMS Client key installation command will look like this:

kms client key

Step 2

You can skip this step if your DNS has a valid SRV record that allows clients to find the KMS server.

Tip. You can check this DNS entry using command:

nslookup -q=SRV _VLMCS._TCP.theitbros.com

If the client does not find the KMS server automatically, then you can specify the address of the KMS server manually:

slmgr /skms <KMS_server_name_or_IP>:1688

address KMS server

Step 3: Activate Windows on KMS server

To activate Windows with KMS server, run the command:

Slmgr /ato

And wait until message Product activated successfully appeared.

address KMS server

Step 4: Check the Status of Windows Activation

Optionally, you can display information about the status of Windows activation:

slmgr /dli

activation windows KMS server

Most often when users facing following errors when activate Windows with KMS server:

  • 0xC004F074 The key management server is unavailable. It means that the KMS service on the server is not running or access to it from the client is blocked (check TCP port 1688 availability on server);
  • 0xC004F038 You did not have the necessary number of systems to activate (for client versions of Windows minimum number of KMS clients- 25, for Windows Server – 5).

Note. The KMS license activation server (Key Management Service) allows you to activate corporate versions of Windows operating systems and Microsoft Office products within the enterprise network.

The main advantages of KMS activation:

  • KMS clients do not need to access the Internet or the phone to activate the system, only requires network access to the KMS server;
  • In case the KMS server does not work, there is nothing to restore on the KMS server. Just install a new server, install KMS role, enter the key, activate and everything is ready to go!;
  • KMS infrastructure is simple and extensible, one KMS server can serve thousands of clients.

Below are the collection of public KMS Client license keys from Microsoft for all supported Windows versions. They are pretty hard to find using the Microsoft website.
