Microsoft has already introduced quite a few new and useful security features with Windows 11, including a new security feature called Microsoft Defender Application Guard.

This article will discuss Microsoft Defender Application Guard and how to enable it on your system. First, let’s examine what it does.

What is Microsoft Defender Application Guard?

Microsoft Defender Application Guard is a security feature that lets you browse untrusted websites securely using the Microsoft Edge browser. The feature is only active while using the Microsoft Edge Browser and is not linked to other web browsers such as Chrome, Firefox, etc.

When you activate Microsoft Defender Application Guard on Windows 11 and open an application guard window in the Edge browser, it creates a virtual machine using the Hyper-V technology.

Creating a virtual machine isolates your Edge browser session from the main installation. It runs the Edge browser on a virtual machine to prevent hacker attacks or malicious files from accessing trusted resources.

Enable Microsoft Defender Application Guard in Windows 11

Although you may not be fully aware of Microsoft Defender Application Guard, you might want to enable it on your device. Before following the steps, please note that the Microsoft Defender Application Guard uses Hyper-V technology to create a virtual environment.

The feature is only available for Windows 11 Pro, Enterprise, and other variants. Hence, your PC should have Virtualization turned on to enable & use this feature. Here’s what you need to do.
