If you want to learn how to protect your Windows PC from malware attacks while surfing the web on Microsoft Edge, look no further. Microsoft releases two feature updates to its OS annually. Windows 11/10 introduced new features, including Microsoft Edge Application Guard. While the Application Guard itself isn’t new, its widespread availability due to this update is important and relevant.
Microsoft Defender Application Guard for Microsoft Edge
Ransomware began trending last year due to the targeted attacks on businesses worldwide. The Application Guard is primarily a security response to that. When using the Microsoft Edge Browser with the Application Guard on, you’ll be using a separate copy of the OS that doesn’t allow the attacker to enter the corporate network through a local computer. This is done through Virtualization technology.
When a person tries to access a site that is not recognized or trusted, Application Guard creates a new Windows case to run the Microsoft Edge browser. This new Windows process has no access to the user’s normal operating environment, including local storage, domain credentials, installed applications, memory, etc. Simply put, the employee of a corporation will be accessing the particular website in a vacuum, through which an attacker will not be able to gain access to the local system or any other system in the corporate network.
In the era of cyber terrorism, a secure way to access the web has become vital. While no browser is without vulnerabilities, Application Guard gives Microsoft Edge an edge in a competitive market.

If you want, you can also use Ctrl+Shift+A hotkey for the same. This will launch a separate window for the Edge browser and you will start browsing with Application Guard security in Microsoft Edge. You can add more and more sessions using the same steps.
After you select this, your web browsing session will be isolated from your computer. This is done by opening a new virtualized environment. The first time you do this, you might have to wait a few minutes while the new environment is created. After the first usage, though, the sessions tend to open more quickly.
This will not work if your processor doesn’t support virtualization. In this case, the option will be gray when you open the Turn Windows Features on or off window.
When you are done with your browsing session, simply close all the Edge browser windows that you opened with Application Guard.
