Get Office 2021 for FREE without a product key

As you know, in the past fourteen years, all Microsoft Office version numbers were named according to a simple arithmetic sequence that has a difference of 3 between each one since Office 2007. Notwithstanding the rule, a new version of Microsoft productivity suite was released on October 5th succeeding Office 2019 and its official name is Office 2021, not Office 2022. Surely you will be curious to know what is new in this version that makes them change the naming convention of their product. Is it worth upgrading your old productivity suite? Let’s make it clear right now.

What’s new in Office 2021

There are quite a few new features added to this 2021 version. You will have a new dark mode, realtime co-authoring, editing tools, functions, motion graphics, improved features, and so much more. Just check out the official article here for more details. Now I am still using Office 2019 because new things in version 2021 are not enough to convince me to upgrade to it. Perhaps I will consider it again in the future but not now.

Download and install Office 2021

First, make sure that the operating system version you are running is Windows 10 or later before you get started. There is no way to install Office 2021 on Windows 8 or earlier.
Just go here to get the official download link from Microsoft. The size of the IMG file is 4.2 GB. Double click on the file to mount it to a virtual drive on your PC once the download is complete. Then follow the instructions of the Setup Wizard to install Office 2021 on your Windows.

This might take a while, please wait.

After the installation completes, just open an Office app to verify some basic information. Just skip the product key option by clicking the X button at the top right corner.

As you can see in the screenshot below, I installed Office Professional Plus 2021 on my PC successfully and the trial license will expire in 7 days.

Activate Office 2021 for FREE using KMS client key

Method 1: Running CMD commands manually

Running commands manually to activate Office 2021

Step 1.1: Open cmd program with administrator rights.
First, you need to open cmd in the admin mode, then run all commands below one by one.

Run cmd program with admin rights
Run cmd program with admin rights

Step 1.2: Get into the Office directory in cmd.

cd /d %ProgramFiles(x86)%\Microsoft Office\Office16
cd /d %ProgramFiles%\Microsoft Office\Office16

If you install your Office in the ProgramFiles folder, the Office directory depends on the architecture of your OS. If you are not sure of this issue, just run both of the commands above. One of them will be not executed and an error message will be printed on the screen.

Step 1.3: Install Office 2021 volume license.

for /f %x in ('dir /b ..\root\Licenses16\ProPlus2021VL_KMS*.xrm-ms') do cscript ospp.vbs /inslic:"..\root\Licenses16\%x"

This step is required. You can not install the KMS client product key of Office without a volume license.

Step 1.4: Activate your Office using the KMS key.
Make sure your device is connected to the internet, then run the following commands.

cscript ospp.vbs /setprt:1688
cscript ospp.vbs /unpkey:6F7TH >nul
cscript ospp.vbs /inpkey:FXYTK-NJJ8C-GB6DW-3DYQT-6F7TH
cscript ospp.vbs /sethst:107.175.77.7
cscript ospp.vbs /act

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 “act” again until you succeed.

Here is all the text you will get in the command prompt window.

  1. Hi Guang,

    1. May I know your above script is able to activate both the LTSC Visio Pro 2021 and Project Pro 2021 besides MS Office Pro Plus 2021?
    2. Do I need to log to use the app?

    Thanks in advance.

    Best Regards..

  2. just installed and activated successfully by following the instructions. The batch file script method does not work, you will need to input all commands into cmd one at a time as per instructions and will get the license activated.

  3. I have been using this for a long time. But today I noticed a warning sign which is not present before. It is showing that “Your license is not genuine, and you may be victim of software counterfeiting. Avoid interruption and keep your files safe with genuine office today.”
    But it is volume license. So it should not be showing that message. Right?

    1. Many of you have the non-genuine license problem. For my part, I have installed and activated Office 2021 on several PCs for several months with the script above, I have made the updates, so I have the latest version of Office and I do not have the not genuine license warning, everything is fine.

  4. Hello, and thanks for this! Per your comment here “The Office 2021 KMS license is valid for 180 days only but it can be renewed automatically so you needn’t worry so much about the period.”

    Will I have to run the script/activator again in 180 days, or does it renew on its own without any user intervention?

    at the end I get this my ms-office is not activated

  6. hi bro, I have pre-install Microsoft office home and student 2021 but it has not been activated. I try many activation codes. plzz guide me to activate the ms-office

  7. I have used this activation method in the past.

    However, I have found I am now unable to activate Office when following the steps provided.

    As this method now appears to not be functioning correctly could you please provide further information or an update to enable activation of Office

  8. Hello guys,
    In the command line I see that the office is licensed. And everything is OK.
    But when I open any Office app, it stands that office is not activated and I need to add a product key.
    When I enter the provided product key, it says that this key is for a volume-licensed version of LTSC office, and it’s not this version.
    Could somebody help me?

      1. I read it and followed it precisely. But after the initial installation and closing the popup window, I had no grace period. Just a message that the office is in view mode and needs to be activated. Then I closed the Word app and followed the next steps. And it stated that activation was OK. But after opening the Word app or any other app the activation popup appeared repeatedly.
        After all the issues I completely uninstalled Office 2021, and installed Office 2019. Looks like it installed a 32-bit version. And it was activated successfully. Maybe the reason is in 64-bit version of Office 2021.

      2. Yep, I like Merlin and others did read all the instructions. However, although the cmd shows that the product is activated when launching any office product, word, exel, etc a pop-up window shows that a key is required for activation.

        Does anyone know if any changes can be made to the script that will allow activation of office?
