    Does anyone have a link to show how to use PowerShell to tweak the Windows Defender settings (for Windows Home users). I am currently doing this in .REG files but would like to write a nice script.

    It would be nice to see all these powerful settings in the UI.
    But for now, Group Policy and PowerShell are needed to configure settings.

    There are two Windows Defender Exploit Guard Group Policy folders, both named the same.
    For the Attack Surface Reduction rules, open the Windows Defender Group Policies.
    It's then the bottom folder within the Windows Defender folder.
    In here you will find three of the Windows Defender Exploit Guard features' settings (those that are implemented as part of Windows Defender), including the Attack Surface Reduction rules.

    Then pick the rule IDs you need from the Microsoft Docs documentation linked to earlier and activate.

    It has been a long time since font parsing was done in kernel mode.
    Dropping the “Untrusted Font Blocking” setting

    Good advice. :thumb: Also - when in doubt, try Audit mode first instead of going straight to Block mode. :)

    It would be great if you could make a simple SW (like GFlagsX) to allow Home users to set up WD as easily as Pro users :)
    Here you can download the two registry keys to set the high cloud blocking level:

    Agreed, that would be nice to have a simple UI to toggle those low level Defender settings more easily.

    Has anybody had much time yet to play around with the new Attack Surface Reduction (ASR) rules?
    Link: https://docs.microsoft.com/en-us/wi...exploit-guard/enable-attack-surface-reduction

    It seems that the requirement for ASR in particular is that you have to be running Windows Defender Antivirus for these to work. I prefer not to run Defender, and therefore I can still make use of the Exploit Guard mitigations. But unfortunately not these ASR rules. These rules are quite nice though. You can exclude files and folders as well which is great.


    You can manually add the rules by using the GUIDs in the following table:

    Rule description GUIDs
    Block executable content from email client and webmail
    BE9BA2D9-53EA-4CDC-84E5-9B1EEEE46550

    Block Office applications from creating child processes
    D4F940AB-401B-4EFC-AADC-AD5F3C50688A

    Block Office applications from creating executable content
    3B576869-A4EC-4529-8536-B80A7769E899

    Block Office applications from injecting into other processes
    75668C1F-73B5-4CF0-BB93-3ECF5CB7CC84

    Impede JavaScript and VBScript to launch executables
    D3E037E1-3EB8-44C8-A917-57927947596D

    Block execution of potentially obfuscated scripts
    5BEB7EFE-FD9A-4556-801D-275E5FFC04CC

    Block Win32 imports from Macro code in Office
    92E97FA1-2EDF-4476-BDD6-9DD0B4DDDC7B

    See the Attack surface reduction topic for details on each rule.

    You have to review event logs to determine what has been blocked. Whereas in WD ATP:

    You are welcome, @Djigi :)

    As far as I can see from your posts, you have activated all the new features now.
    The only thing I didn't see you mentioning activating, are the new Network Protection.
    It has a subfolder in the same Windows Defender Exploit Guard Global Policy folder, where you also have the subfolder with policies for Attack Surface Reduction rules.

    Whenever a Attack Surface Reduction rule are triggered, there's a notification in Action Center and also a log entry made in Event Viewer.
    So you will be notified of all blocks being made. :thumb:

    Maybe Microsoft servers are busy, everyone wanna update now :p
    I'd wait at least for the first patch Tuesday, so that most bugs can be reported and fixed :)

    Yes, couple of this now stuff I did turn on.
    That ASR got couple of stuff what is useful for me (maybe), and that is:
    - Block executable content from email client and webmail
    - Impede JavaScript and VBScript to launch executables
    - Block execution of potentially obfuscated scripts

    I don't have any Office app and use only Gmail Online mail.

    Also, I have a question about that Exploit protection and Google Chrome.
    I added chrome but don't know what security options to turn ON?
    I added this (screenshot) but it brake all my extensions so I turned all off.

    I had to disable Control Folders Access. Its prompts any time I clicked on files or apps in protected folders, it felt like UAC on steroid. Also I was unable to delete new files that I created and saved in protected folders after the upgrade. Not allowed to send them to the recycle bin or by right click and select delete, explorer shell delete option not available. There maybe an easy way to deal with it but I could not find it.
