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

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. The new installation includes a 30-day free trial license by default. 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.

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. 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 servers 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

Step 1.1: 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.

open cmd as admin
open cmd as admin

Step 1.2: 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
Open your Office folder
Open your Office folder

Step 1.3: 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"
Convert Office license
Convert Office license

Step 1.4: 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:s8.uk.to
cscript ospp.vbs /setprt:1688
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.

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

Step 2.1: Copy the code below into a new text document.

Step 2.2: Save it as a batch file. (eg. office365.cmd).

Save the text file
Save the text file
Set name of the batch file
Set name of the batch file

Step 2.3: Run the batch file with admin rights. (important!).

Run the batch file as admin
Run the batch file as admin

Done! Your Office is activated successfully.

Successfully activate Office 365
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.

If you would have any questions or concerns, please leave your comments. I would be glad to explain in more details. Thank you so much for all your feedback and support!

  1. It doesn’t work on mine VM. So i install o365 but when i run all the activating command i get product activation succesful. When i open O365 it says not activated. So i saw tath this key cscript ospp.vbs /inpkey:XQNVK-8JYDB-WJ9W3-YJ8YR-WFG99 is for office 2016 and not for O365. And on the end of the video office 2016 is activated not O365.

  2. Hello, I appreciate the work that you do here. I have a question. Currently, I have the Office365 version installed on my computer, but when I checked the product information, it says “Microsoft Office LTSC Professional Plus 2021” instead of Office365 license or somewhere along those lines, why is that?

  3. I have a Issue Here:After Activated the office 365 ,All New Functions Works Well,But After Some time all new functions missing like:
    =_xlfn.UNIQUE(_xlfn.TOCOL(A4:C6)).
    Anyone encountered the same issue ?
    Please share your solution.Thanks

  4. So uhh it doesn’t work for me
    Downloaded Office 365 ProPlus version and did the steps
    But for some reason it still asks for a product key

    So I use this XQNVK-8JYDB-WJ9W3-YJ8YR-WFG99 to try it and it gives the ERR message “Product is for the volume licensed version of Microsoft Office ProPlus 2016, not currently installed on your computer”
    Pls help

  5. I know the last 5 characters in the included 5-day grace period product key are VMFTK. Can you change the product key to the actual Office 365 key?

  6. According to the video above, the product key on this page is actually from Office 2016, not Microsoft 365. Can you change the product key to the one has Office 365 ProPlus (now Microsoft 365 Apps for enterprise)?

    1. You’re right, this is Office 2016 license.
      First time I was surprised because I use the same Office16 at work, and when I logged in, I felt strange and quickly realized this is not Office 365. 🙁
      I’m happy anyway because the Office is working and it is a very nice code snippet.

      If you manage to upgrade to Office 365, I’m ready for it!
      Thank to @Always Smile

  7. I just want to thank the people behind this post, I am grateful to have an office-activated account finally. This will surely help with my documents as I am currently taking up a course at a university. I hope more people will come and discover this helpful post!
