In this guide, we’ll explore how to legally use Microsoft Office 365 for free. Initially, you can download and install Office 365 using an online installer directly from the Microsoft homepage. This installation comes with a 30-day free trial. After the trial, essential features will be disabled unless you subscribe to Office 365. If you’re facing financial difficulties, this can be a challenge. To help you continue using Office 365, we recommend using a KMS license key for activation.

A KMS license is free, legal, and valid for 180 days. It can be renewed easily, allowing continued use without interruption.

1. Remove Your Current Trial License

If your trial license has expired, you can skip this step. If it is still valid, you need to remove it to avoid any issues during activation with the KMS license. Instructions for removing the trial license can be found in our previous posts.

2. Prepare Your Computer

Ensure your internet connection is stable and that the Windows Update service is enabled. KMS licenses require verification via an internet connection to a KMS server. Check if the KMS server is accessible by visiting http://kms8.msguides.com. If visible, the server is not blocked.

3. Activate Office 365 Using KMS Client Key

Manual Method

Step 1.1: Open Command Prompt as Administrator

• Right-click the Start menu and select “Command Prompt (Admin)”.
• Follow the instructions below, copying and pasting the commands into the Command Prompt.

Step 1.2: Navigate to Your Office Folder

• For a 32-bit version of Office

cd /d %ProgramFiles%\Microsoft Office\Office16

• For a 64-bit version of Office

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

Step 1.3: Convert Your Office License to a Volume License (if necessary)

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"

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:107.175.77.7
cscript ospp.vbs /setprt:1688
cscript ospp.vbs /act

If you encounter error 0xC004F074, it indicates that your internet connection is unstable or the server is currently busy. Ensure your device is connected to the internet and try running the “act” command again until it successfully completes.

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
