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 shown you guys how to download and install Office 365 Multi-language using online installer downloaded directly from the Microsoft homepage. By default, the new installation includes a 30-day free trial license. After that, 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: http://kms8.msguides.com. If it is visible, this means my KMS server is not blocked.

Activating your Office 365 using KMS client key

1. Manual method

Time needed: 1 minute.

Manually activate your Office 365 using KMS client key.

  1. Open command prompt as admin.

    First, you need to open command prompt with admin rights, then follow the instruction below step by step. Just copy/paste the commands and do not forget to hit Enter in order to execute them.

  2. Navigate to your Office folder.

    If you install your Office in the ProgramFiles folder, the path will be “%ProgramFiles%\Microsoft Office\Office16” or “%ProgramFiles(x86)%\Microsoft Office\Office16”. It depends on the architecture of the Windows OS you are using. If you are not sure of this issue, don’t worry, just run both of the commands above. One of them will be not executed and an error message will be printed on the screen.

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

  3. Convert your Office license to volume one if possible.

    If your Office is got from Microsoft, this step is required. On the contrary, if you install Office from a Volume ISO file, this is optional so just skip it if you want.

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

  4. Use KMS client key to activate your Office

    Make sure your PC is connected to the internet, then run the following command.

    cscript ospp.vbs /inpkey:XQNVK-8JYDB-WJ9W3-YJ8YR-WFG99
    cscript ospp.vbs /unpkey:BTDRB >nul
    cscript ospp.vbs /unpkey:KHGM9 >nul
    cscript ospp.vbs /unpkey:CPQVG >nul
    cscript ospp.vbs /sethst:kms8.msguides.com
    cscript ospp.vbs /setprt:1688
    cscript ospp.vbs /act

    Here is all the text you will get in the command prompt window.
    C:\Windows\system32>cd /d %ProgramFiles%\Microsoft Office\Office16
    C:\Program Files\Microsoft Office\Office16>cd /d %ProgramFiles(x86)%\Microsoft Office\Office16
    The system cannot find the path specified.

2. Using batch script

This method is not recommend anymore due to the new update of Microsoft.

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

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

Save the text file

Set name of the batch file

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

Run the batch file as admin

Done! Your Office is activated successfully.

Successfully activate Office 365

Note:

  • 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.

    I’ve tried reinstall the office 365 (directly from Microsoft’s page) and I’ve executed the commands by the manual method. It not worked. What can I do?

    Doing this converts the Office 365 (2019) Pro Plus edition to Office 2016 Pro Plus VL; and removes several features of Office 365 (2019) Pro Plus Edition. The serial key is for 2016 edition VL, not for 2019 edition or latest 365.

      Install Office Pro plus will automatic upgrade to Office 2016 pro plus or Office 2019 pro plus, this is the main feature of Office 365 pro plus. When come up new version of Office, will keep on upgrade. No need to change the key for new version. Even you buy retail version of Office 365 pro plus, will get the same result.

    Hi, I installed office365proplus via your office deployment guide method, I had activated office multiple times with this method, even activated for a friend 1 days ago, but now I’m getting following error via the batch script method – “Sorry! Your version is not supported.
    Please try installing the latest version here: bit.ly/odt2k16”.

    Also, got licence consumption error via manual activation, kindly help.

        Ok, after busting my head for the last 5-6 days to resolve the “We’re sorry but excel has run into an error that is preventing it from working correctly” error, it gave me the following options – “Repair Now, Help & Close”.

        Tried all possible online solutions, uninstalling office completely, repairing etc., installing office 2016 from your .iso download file, what finally worked for me was installing Office 2019 from your .iso download link.

        I was able to successfully activate it too with your kms manual activation method for 2019, everything is working as expected, also, installed office updates.
        Thanks a lot for sharing this with us here on your site.

        Only thing I noticed is, I installed from the setup after mounting the.iso, it automatically installed the 32 bit version, even though my OS is 64 bit, but I’m happy as that doesn’t matter to me.

        Thanks again for your work.

          If yours windows system is 32 bit, it automatic installed 32 bit version. Otherwise, you can choose between 32 bit or 64 bit install.

            I know, but it picked the 32 bit version automatically, but my windows OS is 32 bit, never mind, I think 64 bit had some issues, I’m happy until it works without any issues.

    As this is KMS licence. How much will it work. For 180 days? What to do after that? Btw which organization KMS is this?

    Reply
    1. Kwong

      after 180 days, anytime you online again, it will reactivate back to 180 days.

      Anyone buy KMS Host key from Microsoft can run their own server.
