Activating all versions of Windows Server without a 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 keys. 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 instructions below.

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.

How-to video

Step 1.1: 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.

Step 1.2: 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.

Open cmd with admin rights
Open cmd with admin rights
run command slmgr ipk
run command slmgr ipk

Step 1.3: Set the KMS server.
Enter “slmgr /skms kms8.msguides.com” in the window.

run command slmgr skms
run command slmgr skms

Step 1.4: Activate the KMS client key.
Finally, use the command “/ato” to activate your Windows.

run command slmgr ato
run command slmgr ato

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 2.1: Copy all the text below into a text file.

    You can also successfully activate Windows 10 pro version using the same KMS activation cmd. Works like charm!!!

  2. Hey champ,

    After successful activation of my Office LTSC 2021 using your tutorial, I came across this tutorial on activation of Windows servers.
    Kudos to you again.. It worked like charm.
    Thanks a ton, Guang…

    P.S. Earlier I used to see “Activate Windows” on my lower right corner of my screen. Now, it is totally vanished after the activation!!!!

  5. server 2022 standard key VDYBN-27WPP-V4HQT-9VMD4-VMK7H will activate if done manually, but the script says not supported. but it is. can you fix the script ?

  6. I paid for server-2003/2008/2012/2016 and never got credit to use for an upgrade when it came time for 2016 to expire, I found you. I work for a nonprofit and sometimes the work is 24/7. They have no more money because of the state of the world and so many people in need. You just helped a lot of people. The cost of Win Server feeds many and provides meds. Thanks again.

    Thank you, friend. Very much.
    Happy New Year

  7. Hi Guang,
    thanks a lot for the detailed instructions. Worked fine for Windows 2022 DC. It was annoying to always re-install the server after the 180 days of evaluation period was gone. Even for testing purposes that may last longer than the granted 180 days.
    1 question is remaining: What happens if MS asks you to shut down the webpage/KMS server or if you do this on your own ? Because when I cut the internet connection and changed the system date to 2025 Windows told me that the system cannot be activated because the KMS server is not reachable

  8. every time i enter slmgr /ipk windows key it says windows script host disabled in this machine contact your administrator can you help me to remove this i tried to do the regedit thing but it didnt work

  9. Hello –

    Thank you so much for setting this up. It’s very helpful. However I am stuck and could use some guidance. I have a Windows 2016 DataCenter Server Eval which I have setup as Primary DC running as a VM. I purchased a license for Standard 2016 assuming that I should be able to convert from DataCenter Server Eval to Standard Retail. I followed the slmgr /upk and then slmgr /ipk and got a non-core edition error. Didn’t realize before that DataCenter Server Eval can only be converted to DataCenter Server Retail and not Standard. What are my options at this point? I tried running the notepad file, it says, Sorry, your version is not supported. Any guidance will be much appreciated.

    Respectfully,

    1. don’t use standard key… instead use “W269N-WFGWX-YVC9B-4J6C9-T83GX” key for windows 10 pro and follow the method 1 from above and it will work. It worked for me 🙂
