Legal way to use Office 365 totally FREE, without paying a dime

Posted by in Microsoft Software Products | Last updated on

In a previous post here, I have showed you guys how to download and install Office 365 Multilanguage using online installer downloaded directly from the Microsoft homepage. By default, the new installation includes a 30-days free trial license. Afer this period, most important features will be disabled. It means your work will be discontinued unless you pay for Office 365 subscription. If you are in financial difficulties, this is so bad, I know. To help you overcome this problem, I recommend using KMS licene key to activate your Office. For those of you guys who don’t already know, KMS license is almost similar to the trial one. It is totally free, legal and is valid for 180 days only. But don’t worry about the period because it can be renewed easily.

Ok! The introduction is over. Now let’s get started!

Remove your current trial license

This step is optional if your trial license was expired. However, if it is still valid, you need to remove it. Because in some cases, after you activate your Office using KMS license, important features are resumed but the expiration notification still remains. Please follow instructions in this post to uninstall the trial license.

Make sure your computer is ready

You need to check your internet connection again and make sure that the Windows Update service is turned on. KMS license has to be verified by making a connection to my KMS server before it can be used. So you need to check if the KMS server is blocked or not. This is pretty simple. Just open your internet browser and try visitting this site: If it is visible, this means the server is not blocked.

Activating your Office 365 using KMS client key

Step 1: Copy the code below into new text document.

create a new text file

Step 2: Save it as a batch file. (eg. office365.cmd)

save this text file as a batch fileset this batch file name is "office365.cmd"

Step 3: Run the batch file with admin rights. (important!)

run the "office365.cmd" file with administrator rights

Done! Your Office is activated successfully.

product activation successful


– I only test this method with Office 365 ProPlus version. I am not sure it will work with the others.

– Step 3 is flagged “important” because the UAC system will stop this process if you don’t do it.

How to renew your Office 365 license

By default, your license will be renewed automaticaly every seven days but in some cases, it can be stuck. So you need to renew the license manually. Just follow instructions here.

    Thanks a lot it worked perfectly for me.

    Few questions :

    – Will I have to re activate after 180 days?
    – Can I install the updates? I assume yes but I want to be sure.

    1. kWong

      Activate will automatic renew back to 180 days every seventh day when you online. Update just like buy retail version from Microsoft.

    Oh my goodness. I have been looking for ways to reactivate my office 365 for like months already (I gave up when other blogs disappointed me) but your blog is a lifesaver… Super thank you… I’m not really a technology-oriented person so I am really thankful that I stumbled on your article/blog. Thank you again.

    My 0ffice 365 Pro Plus did not activate.
    I followed the steps outlined.
    what could be the issue? please help.

    1. Kai Lin

      Hi kWong, i have the same isse as Blinkz . Does it make a difference if i am on office 365 and not Pro Plus?

  8. delc

    when i try to activate my office365 proplus
    office 2016 is getting activated
    how to get rid of this?
    i have removed/uninstalled all the previous versions of my office and freshly installed office365 proplus
    but still im facing this problem

    1. kWong

      When you install Office 365, it will also updrade to office 2016 or office 2019 (for windows 10), so using office 365 batch to activate, office will activate office 2016. Just because office 365 is the only version can updrade to office 2016 , office 2019 , or future Office version.

      1. Ashal Naveen

        Then how to overcome and resolve the problem. ??
        Suggest me
        I want to activate only office 365 pro plus but not
        Office 2016

        1. kWong

          why you want to do this way? Office 365 by default is automatic update and upgrade. That is the reason whey you install Office 365 will become Office 2016 or Office 2019 (windows 10). After complete install, It shown up Office 2016 because Office 365 is in the market for very long time. The retail version of Office 365 will also upgrade to Office 2016 and Office 2019 according your Windows version. If you can use Office 365 batch file activated the Office 2016, that is Office 365 base Office 2016 can have future feature update. But if you Office 2016 batch file to activated, It will become Office 2016, won’t get any new feature update anymore.

          If you only Office 365, before you install Office 365, disconnect internet. After Installation, change Office 365 update setting to stop update forever. And reconnect internet, run Office 365 batch file with admin right to activated.

          Office 365 without any update or upgrade, pay monthly or yearly customer, no one interest to use it. Can’t update or upgrade , better install stand alone Office 2016 instead.

    Why I cannot get the new 2019 Office 365 UI?! At first I got the new UI, but now I have to deal with the previous UI! Is there any way to force the new 2019 Office 365 UI?

    1. Brian Gimao

      Or I meant to say, Office 365 is continuously reverting to Office 2016! Is there any way to force back Office 365?

      1. kWong

        Only windows 10 can run Office 2019. Up to windows 8.1 only can upgrade to Office 2016.

        If you use Office 365 batch file to activated, you still have new features add in coming future.

        Can upgrade to future Office version is the selling point of Office 365. If you want to go back to Office 365, it is no point to install Office 365.
