3 Way to Activate Microsoft Office 2021 without Product Key

Microsoft Office is an essential software suite that includes various applications like Word, Excel, PowerPoint, and Outlook. The latest version of Office is Office 2021, which offers advanced features and functionalities to enhance productivity. However, to access all the features, you need to activate Office 2021 with a product key, which can be expensive. Fortunately, there are several methods available to activate Office 2021 without a product key. In this article, we will explore these methods in detail.

Understanding Product Activation in Office 2021

Before we delve into the methods to activate Office 2021 without a product key, it is essential to understand the concept of product activation. When you install Office 2021, it prompts you to enter a product key to activate the software. Product activation is a security measure designed to prevent software piracy. When you activate Office 2021 with a product key, Microsoft verifies the key to ensure that it is genuine and not being used on multiple computers. If the product key is valid, Office 2021 activates, and you can access all the features.

Use a CMD Command

You can also activate Office 2021 without a product key using a Command Prompt (CMD) command. To activate Office 2021 using a CMD command, follow these steps:

Step 1: Open CMD Program with Administrator Rights

The first step is to open the Command Prompt (CMD) program with administrator rights. To do this, right-click on the CMD program and select “Run as administrator.

Step 2: Get into the Office Directory in CMD

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

After opening the CMD program with administrator rights, you need to get into the Office directory. If you have installed your Office in the Program Files folder, the Office directory depends on the architecture of your OS. If you are not sure of this issue, run both of the commands below. One of them will not be executed, and an error message will be printed on the screen.

Step 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"

Before installing the KMS client product key of Office, you must have a volume license. Without a volume license, you cannot install the KMS client product key of Office. Hence, this step is essential.

Step 4: Activate Your Office Using the KMS Key

After completing the above steps, you can activate your Office using the KMS key. Make sure that your device is connected to the internet and 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:e8.us.to 
cscript ospp.vbs /act

If you encounter the error 0xC004F074, it means that your internet connection is unstable or the server is busy. Please ensure that your device is online and try running the “act” command again until you succeed.

Congratulations! Your Office 2021 volume license has been successfully installed and activated using the KMS key. Now you can enjoy all the features and benefits that Office has to offer.

In conclusion, installing and activating Office 2021 volume license using a KMS key is a simple process that anyone can do. By following the steps outlined above, you can successfully install and activate Office on your device.

Method 2: Use a Batch Script

Another method to activate Office 2021 without a product key is to use a batch script. A batch script is a program that automates repetitive tasks in Windows. To activate Office 2021 using a batch script, follow these steps:

Step 1: Copy the script code below

Step 6: The MS Office 2021 activation process will take a few minutes to complete. Once you see the message “Product activated successfully” as illustrated below, it means that the activation has been successful.

  • Microsoft Toolkit


It is possible to activate Office 2021 without product key, but it requires a certain level of technical expertise. We have examined different approaches, such as utilizing KMS client keys, codes, and third-party software. However, it is crucial to comprehend the potential hazards associated with each method and make sure that you adhere to Microsoft’s license agreement.
