Activating all versions of Windows Server without a product key

Activating all versions of windows server for free without product key

As you know, Windows Server is a specialized operating system which is designed for server only. In today’s post, I will show you how to activate Windows in your VPS or dedicated server for FREE using KMS client product key. Although the KMS license is valid for 180 days only but there is no limit on the number of activation. So you can renew it whenever you want. Actually, the license will be renewed automatically every 7 days by default (almost similar to Let’s Encrypt certificate). In this way, just do it one time and forget it completely.

Note:

  • If you are a student, an office worker or any standard user who is using desktop edition of Windows, just skip this post and please do not follow the instructions. I will not be responsible for any damage caused by you.
  • All editions of Windows Server in the Microsoft homepage are evaluation ones and not supported by KMS. So if you are using an evaluation version, just convert it to the retail one before following the below instruction.

Supported products:

  • Windows Server 2022/2019/2016.
  • Windows Server, version 1809, 1803, 1709.
  • Windows Server 2008/2012 (R2).

As you can see in the image above, I am using Windows Server 2016 Standard and it is not activated.

Method 1: Manually installing KMS client key and activating it.

Legal way to use Windows Server for FREE

Time needed: 1 minute.

Running KMS commands in command prompt manually

  1. Get the right product key from the official article of Microsoft.

    The KMS Client Setup Key of Win Server 2016 Standard is “WC2BQ-8NRM3-FDDYY-2BFGV-KHKQY”. I will use it in the next step.

  2. Install the key on your server.

    To open command prompt, click on the Windows button, search for “cmd” and run the command prompt as administrator. Then, enter “slmgr /ipk CLIENTKEY” in the command window.
    Note: each command is followed by hitting Enter.

  3. Set the KMS server.

    Enter “slmgr /skms s8.now.im” in the window.set kms8 as main kms server

  4. Activate the KMS client key.

    Finally, use the command “/ato” to activate your Windows.

If you see the error 0xC004F074, it means that your internet connection is unstable or the server is busy. Please make sure your device is online and try the command “ato” again until you succeed.

Method 2: Using a pre-written batch file.

This one is not recommended anymore due to the new update of Microsoft.

Step 1. Copy all the text below into a text file.

  2. Guang, what do you mean by “If you are a student, an office worker or any standard user who is using desktop edition of Windows, just skip this post and please do not follow the instructions.” In note sections at the beginning?? I dont really understand that part…

    1. It means that if you are using standard windows, don’t use this; instead use the normal windows activation guide.

  4. PLEASE HELP ME – I want to install Windows Server 2019 Standard for our small non-governmental group. We don’t have enough money to buy original from Microsoft. If I use this method and activate it – will this work just as same as Original from Microsoft? Will it have the same features? How many cores does this have?

    Reply
    1. Hello! Yes it works like thepurchased Activation. You can use it now without any restricitions! It does have that much cores like your processor.

  8. Hello,

    What will happen if kms8.msguides.com is down? Is there a way to create a KMS server locally on the network for such case?

    Thank you

    Reply
    1. There are KMS7, 8, 9.msguides.com for KMS activation.

      Create your own KMS Server, you need buy KMS Host key from MIcrosoft To run KMS Server.

  9. Thanks a lot for your guide. Just a question.
    What happen, if i leave my win 2019 server, always disconnected from internet ?
    Do it stop to works after 180 days ?
    Thanks.

    Reply
    1. Any time after seven day success activation, when you turn on your windows server, connect internet, it will automatic activate back to 180 days. If you insist your windows server, after activation, not connect internet anymore, is no way to get update from Microsoft.

    Reply
    1. Run the batch file with admin ID without restriction online, otherwise won’t work.

      Where did you get windows server iso file?

      Please be noted that Windows Server Evaluations versions are not supported because they have been attached 180-day trial license.

      Reply
      1. You can change the version to retail using PowerShell after installing the Evaluation version on the microsoft website.

        Ignore steps 1-3 above and do the following:

        To determine installed edition name, type the follwoing in PowerShell:
        dism /online /get-currentedition

        To determine possible Target Edition names, type the following:
        dism /online /get-targeteditions

        Using the KSM Client Server Key (I’m targeting Windows Server 2019 Datacenter) relevant to the target version you are after, type:
        dism /online /Set-Edition:ServerDatacenter /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /AcceptEula

        where the above product key is the KSM key for Windows Server 2019 Datacenter taken from the supplied link in the article.

        If you then follow from “4.Activate the KMS client key”

        Your retail version taken from the evaluation install will now be activated.
