How To Activate Microsoft Office Without Product Key for Free

In this step-by-step guide to activate Office without a product key. Note that these methods work on all versions of Microsoft Office. With these methods, you don’t need to buy anything or enter a product key. So, follow the instruction as it applies to your situation.

Before you begin

Before you begin, make sure you’ve installed a Microsoft Office version on your computer. You can visit below download page to download all Office versions then install it.

Method 1: Using a PowerShell script

The first method to activate an Office license is by using a PowerShell script. With this script, you can activate all Microsoft Office versions (2013, 2016, 2019, 2021, and later). The advantages of this method are:

  • There’s no need to disable real-time protection in the Windows Security Center since our activation methods don’t rely on any crack tools.
  • No need to turn off the Windows Firewall or editing the hosts file.
  • The script is capable of activating all editions of Microsoft Office.
  • The script can be used to activate either Office 64-bit or Office 32-bit.
  • You don’t need to know which Microsoft Office edition you’ve installed (Pro, Plus or Standard…). Script detects your Office edition automatically then activates it.
  • The script will convert Office Retail to Volume then activate it automatically.
  • The KMS license remains valid for 180 days and will renew automatically before it expires.

All you need to do is right click on the Windows Start icon, select ether Terminal (Admin) or PowerShell (Admin) to open a new PowerShell window in elevated mode.

Right-click the Start button — or press ⊞ Win + X

Then run the below single line command to activate all Microsoft Office version permanently for free without any 3rd software or activation tools.

Method 2: Activate using batch script (CMD)

Another option is to use a batch script to activate the Microsoft Office license. While this method is no longer recommended because of a recent Microsoft update, it can still be used for automation if necessary. If you decide to proceed, follow these steps:

1. The first step is to download the activation batch script to your computer by clicking the download button below.

For Mac Users – Use the VL Serializer Tool

If you are a Mac user, the VL Serializer tool is the best tool to activate Microsoft Office. The Volume License Serializer is an easy activation method that activates the Office on your PC using a volume license key. Typically, this method is used by organizations and enterprises.

The VL Serializer is a small tool that activates the version of Office installed on your Mac. It allows users to deploy a pre-activated copy of Office on a given Mac computer. As such, you won’t see any activation prompt when you open the copy of Office.

1. Download the Office for Mac installer and VL Serializer from this download page then Install Microsoft Office on your Mac.

2. Once the Office for Mac has been installed, open the Serializer and click Continue to install.

Conclusion

Hello Friends! My name is Leo, and I’m excited to share everything I know about activating Microsoft software products. In the past, I managed several YouTube channels on this topic, but they were taken down by Microsoft. That’s why I decided to start this blog to keep the conversation alive without interruptions. I’m committed to sharing my knowledge and insights for as long as possible!

If you have any questions or concerns, feel free to leave a comment or visit my Discord server. I’d be happy to provide more details. Thank you so much for your feedback and support!
