Windows Defender Application Guard to Make Edge the Most Secure Browser

Microsoft is determined to make Edge the most secure browser, with a new feature called Windows Defender Application Guard which would be available for enterprises.

Usually, when an browser-based attack (or any attack for that matter) takes place, not only the data in your device is stolen but also your credentials are used to spread the attack in your network and eventually steal as much data as possible.

With Windows Defender Application Guard, when the user visits a site either by clicking on a hyperlink in mail or through other means, and the link leads to a untrusted site (not listed in the whitelist maintained by the network administrator), Edge would automatically open that site in a completely isolated environment using Hyper-V virtualization technology, says Microsoft.

Application Guard creates a new instance of Windows at the hardware layer, with an entirely separate copy of the kernel and the minimum Windows Platform Services required to run Microsoft Edge.

If the untrusted website is a bad site which runs an exploit kit, and the attack has been successful, the attacker still won’t have access to your stuff beyond the virtual environment. None of your files or local or domain credentials in your normal working environment can be accessed by the attacker.



Since the attack has happened in the isolated/sandboxed or Virtual environment, the Malware which may have been dropped won’t persist after Edge is closed. Everything in that virtual container would be destroyed.

This is a super exciting feature that will make Edge more secure than ever, protecting systems from Zero-day attacks, Ransomware, Malware and vulnerabilities in the Operating System itself. Windows Defender Application Guard would be available (for enterprises) in 2017.

  1. This comment is about something completely different from the Edge browser, but I hope it’s all right to make this comment here, and ask this question:

    Here’s a problem that a lot of people are having, judging from a Google search for a solution.

    Everything works fine with Windows 10 Home Edition. After installing the Anniversary Update, everything also seems to work fine.

    Some people, though, prefer to run netplwiz and eliminate the need to enter a password every time they turn on their computer.

    When we do this, however, we can no longer change the lockscreen picture. The picture is always an awful Microsoft beach scene.

    Many of us have tried every suggestion on the internet in order to resolve this problem, but nothing works.

    What a lot of people do is run netplwiz once again and set it so that a password is necessary. Once that is done, the lockscreen picture can be changed without any difficulty.

    Again, this problem affects people with Windows 10 Home Edition only.

    Many of us with Windows 10 Home would really appreciate it if you could suggest a way for us to set Windows so that no password is needed and the lockscreen can be changed when that is done.

    And I apologize if I’ve posted this comment / question in the wrong place.
