On Windows 11, the "Microsoft Defender Application Guard" feature lets you browse untrusted websites securely using Microsoft Edge.

The feature creates a tiny virtual machine using the Hyper-V technology with enough components to run Microsoft Edge. Using this approach, you can use a version of the browser isolated from the main installation, which you can use to navigate to any website without the risk of hacker attacks or infecting the computer with malware. Furthermore, this feature makes the isolation container anonymous, which means that an attacker won't be able to steal your device credentials.

The only caveat is that this feature is only available for Windows 11 Pro, Enterprise, and other variants, but it's not an option for the Home edition.

In this Windows 11 guide, we will walk you through the steps to enable and use Application Guard on Microsoft Edge.

After you complete the steps, a new window will open with a shield icon next to the address bar, letting you know that you are using Application Guard.

Since you are using a virtualized and isolated session of Microsoft Edge, you won't be able to sync your settings with your profile. However, your favorites will be available when using the feature.

Also, you will be able to download and view files, but only from a virtual machine hosting the browser session. You can't transfer the files to the host computer.

Furthermore, all the settings and changes will be discarded when you restart your computer.
