How to Enable and Use Microsoft Defender Application Guard on Windows 11?

Microsoft Defender Application Guard is a built-in feature of Windows 11 that lets you browse untrusted websites securely using the Microsoft Edge browser. This feature creates a tiny virtual machine using the Hyper-V technology. Using Defender Application Guard, you can use the Edge browser isolated from the main installation. That means you can browse any website without the risk of hacker attacks or infecting the computer with malware. Apart from this, it makes the isolation container anonymous, which means that an attacker won’t be able to steal your device credentials.

However, the problem is that you need Windows 11 Pro or higher edition to use this feature. This feature is not available for the Windows 11 Home edition.

In this gearupwindows article, we will guide you through enabling and using Microsoft Defender Application Guard on Windows 11.

Edge webpage sessions will be virtualized and isolated, so you won’t be able to sync your settings with your profile. However, your favorites will be available when using the feature. Also, you can download and view files, but only from a virtual browser session. You will not be able to transfer the files to the host computer.

As soon you restart your computer, all the settings and changes will be discarded automatically.
