    How to Turn On or Off Windows Defender Application Guard for Microsoft Edge in Windows 10


    Microsoft Edge is a new web browser that is available across the Windows 10 device family. It is designed for Windows 10 to be faster, safer, and compatible with the modern Web.

    Announced last September 27th 2016 in the Microsoft Edge Blog, Windows Defender Application Guard for Microsoft Edge is now available in Windows Insider Previews for Windows 10 Enterprise edition users in the Fast ring.

    Starting with Windows 10 Enterprise build 16188, Microsoft has made it easy to test drive Microsoft Edge with Application Guard.

    Microsoft Edge running in Application Guard provides enterprises the maximum level of protection from malware and zero day attacks against Windows. Windows Defender Application Guard for Microsoft Edge is a lightweight virtual machine that helps isolate potentially malicious website activity from reaching your operating systems, apps, and data.

    There is no persistence of any cookies or local storage when an Application Guard window is closed in Microsoft Edge.

    Three core features of Windows Defender Application Guard:
    • Isolated Browsing - Windows Defender Application Guard uses the latest virtualization technology to help protect your operating system by creating an isolated environment for your Microsoft Edge session.
    • Help Safeguard your PC - Windows Defender Application Guard starts up every time you visit a non-work-related site to help keep potentially malicious attacks away from your PC.
    • Malware Removal - Any websites you visit, files you download, or settings you change while in this isolated environment are deleted when you sign out of Windows, wiping out any potential malware.

    Starting with Windows 10 Enterprise build 16232, Microsoft added support for Microsoft Edge data persistence while using Application Guard. Once enabled, data such as your favorites, cookies, and saved passwords will be persisted across Application Guard sessions. The persisted data will be not be shared or surfaced on the host, but it will be available for future Microsoft Edge in Application Guard sessions.

    Starting with Windows 10 build 17063, Windows Defender Application Guard will now be available in the Windows 10 Pro edition.

    For more details about Application Guard, see:

    This tutorial will show you how to turn on or off the Windows Defender Application Guard for Microsoft Edge security feature for all users in Windows 10 Pro and Windows 10 Enterprise.

    You must be signed in as an administrator to turn on of off the Windows Defender Application Guard for Microsoft Edge security feature.

    In Windows 10 build 16193, Windows Defender Application Guard (WDAG) will fail to work on touch PC’s, showing a solid black window on launch. Non-touch enabled devices should not experience the issue. A temporary workaround if you would like to use WDAG is to go to Device Manager, expand Human Interface Devices and disable the “HID-compliant touch screen” and “Intel Precise Touch Device” if they are present. After a reboot try WDAG again. Re-enable these devices to restore touch.

    Hello @dencal, :)

    The bit below from the release notes of Windows 10 build 17063 indicate that WDAG will not be available to the Windows 10 Pro edition until the next build release instead.

    For now, WDAG is still only available for the Windows 10 Enterprise edition.

    Windows Defender Application Guard (WDAG) update: You spoke, and we listened. Microsoft is bringing Windows Defender Application Guard to Windows 10 Professional in the next feature update of Windows 10. Now, like Windows 10 Enterprise users, Windows 10 Pro Users can navigate the Internet in Application Guard knowing their systems are protected from event the most sophisticated browser attacks.

    To be truthful Brink I had noticed your highlighted "next feature update".
    This conflicts with a note further down concerning this feature.....but I take note of your response.

    It is available now to our awesome Windows Insider community to give it a try and we would like to hear your feedback.

    Yeah, the article they also linked to below states this, but it is dated "12-01-2017 - last edited Tuesday". I guess they decided to wait until the next build release after 17063.

    Announcing WDAG in PRO SKU - Microsoft Tech Community

    Requirements:

    • Windows 10 Professional, Build: 17053 (or later)
    • en-us only for the current builds; full localized support will arrive soon
    • PC must support virtualization; Hyper-V (some older PCs may not support Hyper-V or have this feature disabled in BIOS)
    • Windows Defender Application Guard is Off by default, it must be enabled manually or by policy
    It certainly does confuse this.

    @dencal,

    I just tested in a Windows 10 Pro build 17063 to verify, and I was actually able to enable WDAG after all.

    Brink.
    Unfortunately cannot do as WDAG is greyed out, stating...Cannot be installed: Virtualisation support is disabled in the firmware.


    Added
    Have successfully enabled Virtualisation in the bios and have now New Application Guard window installed.
