    Microsoft Defender Exploit Guard on Windows 10 Pro


    I've recently found that I'm unbale to access certain websites, e.g. Steam due to the following message in event viewer.


    Your IT administrator has caused Microsoft Defender Exploit Guard to block a potentially dangerous network connection.

    Detection time: 2020-09-28T10:54:07.842Z

    User: S-1-5-21-3685733074-3372044061-980300008-1001

    Destination: https://store.steampowered.com

    Process Name: C:\Program Files\Google\Chrome\Application\chrome.exe


    If I try to access via MS Edge I get a big red page:


    This content is blocked
    For your protection, your organisation is not allowing you to access the resource or content hosted by store.steampowered.com

    I have not changed anything on my PC so presume this is some sort of Windows update. If I check Virus and Threat Protection settings or Exploit Proetction it states that it is managed by your administrator, despite it being used for home.


    I have a main MS account for logging in and a workplace account used by other apps.


    I literally cannot work out how to access certain websites. I've checked on my laptop and it's fine, but not on my desktop PC. Does anyone have any ideas?

    :)

  2. Bug? In Windows Defender Exploit Guard.

    If we assume that this is just a glitch, then you might be able to reset the Exploit protection defaults by exporting the settings from an unaffected PC (with default settings) and then importing those settings on the affected machines. This looks
    to be the backup/restore tool for the Exploit protection settings:

    network protection, a feature in windows defender exploit guard, doesn't work right

    In case it still isn’t clear; the Windows IT Pro Center documentation gets cited in discussions of the Windows Defender Exploit Guard features because it’s the most comprehensive documentation for all of these next-gen features, including the Network
    Protection feature. That shouldn’t be taken to imply that any of these technologies are limited to enterprise environments, or that the topic is limited to security administrators. If you’re looking for the simplified documentation, it's right here:

    Enable Windows Defender Exploit Guard Network Protection in Windows 10

    And yes, I can personally guarantee that no Enterprise Security Administrator would ever be caught dead downloading Brink’s
    Enable_Windows_Defender_Network_Protection.reg file. That file is for Windows 10 Home users who are afraid of the PowerShell command line.
