How to Activate Microsoft Office 365 without Product Key

Microsoft Office 365 is a subscription-based software suite that includes popular applications such as Word, Excel, PowerPoint, and Outlook. However, to activate Office 365, you usually need a product key that comes with the subscription. In some cases, though, you might not have access to the product key or lose it. The good news is that there are ways to activate Office 365 without a product key. In this article, we will explore some of these methods and guide you through the process of activating Office 365 without a product key.

Use a Batch File to Activate Office 365

Another way to activate Office 365 without a product key is to use a batch file. A batch file is a script file that contains a series of commands that can be executed by the Windows command processor. Here’s how to use a batch file to activate Office 365:

Step 1: Copy the script code below

@echo off

pause >nul

Step 2: Create a new text document on your desktop by right-clicking and selecting New → Text Document.

Step 3: Paste the copied code into the newly created Text Document file, and then select File → Save as.

Step 4: Save the file in .cmd format, such as activator.cmd, and then click Save.

Step 5: Right-click on the activator.cmd file you just saved, and then select Run as Administrator. Double-clicking with the left mouse button won’t activate it successfully.

Step 6: The Office 2013 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.
