@Andy Ful Is there any option to save settings of Cofiguredefender(CD)? I am confused on how to use it. BTW, CD enabled NIS protection which is a good thing. But most of time, some smartscreen settings to reverted to Block instead of User which I already set using Win security center.
On my Windows 10 Pro machine, ASR rules were resetting to OFF when CD was running. On my Windows 10 Home w/ Gpedit.msc regedit worked fine.
I did delete Local gpedit rules using winaero tweaker and did manually by booting into Linux as well.

The settings are written to the registry in the real-time. Yet, some other security can prevent PowerShell to do it. You can use the <Refresh> green button to see if the chosen settings were applied correctly. If there is a difference in the displayed settings before and after <Refresh>, then something is interfering with PowerShell.
If you have set Defender settings via GPO (Windows Pro) then you have to set those settings to "Not configured" by using gpedit.msc . Let me know If you will have problem with it.
Please, read also the information in the second part of the HELP - I put there some information about GPO and Registry keys.(y)

I'm used to clicking Save and then memorizing each settings. My mem. muscle might be an issue. Then again, how to export current Configuredefender settings so that its easy to restore settings upon clean installing Windows 10?

There is no such option. You have to choose one of the predefined options, and next you can adjust the settings to your needs. I recommend using <Defender high settings>.(y)

I could not get this to install in shadow mode with Appguard off.

EDIT: Was able to pull GUI by running as admin.
ConfigureDefender cannot work with Shadow Defender in the shadow mode, because many Defender options require restarting the system.
It can work with AppGuard when powershell.exe is not protected by Guarded Apps feature. After finishing Defender configuration, the PowerShell protection can be activated again.
The above is true for every PowerShell restrictions - they have to be temporarily turned off to make Defender configuration.

But that turns on controlled folder access that doesn't play nice with RTSS and MSI AB and few others even after whitelisting them in WD.

<Defender high settings> apply Controlled Folder Access in Audit mode - only warnings are displayed that something would be blocked when CFA would be enabled (but it is not). You can simply change CFA setting to Disabled to avoid CFA warnings.

can not get any restart. I have Defender high settings enabled. Appguard is disabled. What setting has to be changed to generate a restart? I am new to using this.
Thanks

I meant the full shutdown and a cold restart = reboot computer = Restart option from the power menu.
Many computers use the Fast Startup mode after Shut Down = Windows signs out of all user sessions, and next saves that state to the hibernation file.
When Fast Start is done many Defender settings are still not activated, also Shadow Defender did not restore your system back to its original state.

Scan all downloaded files and attachments
Sorry if the question has already been asked.
What does this setting do? Set WD to scan the files before they are even saved to the PC, while, if I disable it, files will be scanned only when the download is completed and the whole file is on the local PC?
Thanks :)

Yes, I had the Shadow Defender issue a long time ago and have fast start up turned off. I have a batch file to turn it on and one to turn it off and yes, it take forever for my pc to fully boot up.

If disabled, then after downloading the file it will not be automatically scanned by WD.

@Andy Ful - Today I noticed that exclusions I removed from CFA and ASR kept reappearing. Might this be happening because I am not currently using WD? Or might it be a bug? Or, simple user ignorance? :emoji_thinking::emoji_thinking: :unsure:

BTW: When I use WD, I sometimes access it via Windows Security. When accessing this way using SUA, I only see added folders in CFA from SUA, and when in Admin. Account I see all folders. I suppose this makes sense, but I had not noticed this before.

Some exclusions in ASR, are automatically applied when you press <Child Protection> button or set the rule 'Block executable files from running unless they meet a prevalence, age, or trusted list criteria' to ON. Those rules are deleted when applying <Defender default settings> or <Defender high settings>.

ConfigureDefender does not automatically add/remove the CFA rules.

The default folders (Destop, Documents, Favorities, Music, Pictures, Video) are displayed only for the current account and for the Public account. All entries added manually (files and folders from any user profile) are displayed for all accounts. All manually added entries are stored in the Registry:
  1. HKLM\SOFTWARE\Microsoft\Windows Defender\Windows Defender Exploit Guard\Controlled Folder Access\AllowedApplications
  2. HKLM\SOFTWARE\Microsoft\Windows Defender\Windows Defender Exploit Guard\Controlled Folder Access\ProtectedFolders
You should see the same manually added entries either on SUA or on Admin account.

I tested ConfigureDefender in Windows 10 Insider Build 18841. The Tamper Protection prevents disabling two options:
  1. Behavior Monitoring.
  2. Scan all downloaded files and attachments.
Other options work as usual.(y)
Have you tried clicking Child protection and Configure Defender automatically switches to Max security mode after closing or hitting Refresh. I'm using Home edition.

Child protection = Max settings + SmartScreen set to Block + Hide Security Center.
Defender default settings < Defender high settings < Child Protection.
I recommend using 'Defender high settings'.

Ok... so that was the feature! I thought it was whitelisted system files and its children from being detected as malware. Child Protection = Max web safety and protection for Kids or paranoid users.
