Additional information

Most of these scripts, need to have "Tamper protection" off, as documented in official Microsoft website. (It can be turned on later by user, personal choice.) Note that this issue created, is an addition to the main project. Which means, no duplicate scripts compared to the main project. This feature request is only created to add "missing" values to registry and helping the main project scripts, work better (as intended). Again, all codes checked to prevent duplication in the main script. None of them are duplicate. SIDE NOTE 1 According to this, most of Windows Defender files are located in "C:\Program Files\Windows Defender" so maybe develop a script to purge that location? SIDE NOTE 2 I realized some services (!) are not disabled: MDCoreSvc WinDefend wscsvc SgrmAgent SgrmBroker Also they put some before/after pictures for their script: Before After The script: https://github.com/TairikuOokami/Windows/blob/main/Microsoft Defender Disable.bat Like I found some scripts to remove the "Shell Association" of Windows Defender, which AFAIK, isn't implemented in this project.

@undergroundwires I need to shower.

undergroundwires commented 3 months ago

A lot of userful stuff @femdiya. Thank you for the research. I will release 0.13.6 first then focus on Defender.

One question is PolicyManager keys: HKLM\SOFTWARE\Microsoft\PolicyManager.. These are Intune MDM policies and apply only to remote managed devices such as work and school computers. If see the traditional policies for many of these take AllowRealtimeMonitoring for example. You provided PowerShell -ExecutionPolicy Unrestricted -Command "reg add 'HKLM\SOFTWARE\Microsoft\PolicyManager\default\Defender\AllowRealtimeMonitoring' /v 'value' /t 'REG_DWORD' /d '0' /f". But we already set GPO using Software\Policies\Microsoft\Windows Defender\Real-Time Protection and DisableRealtimeMonitoring value, see docs:

So I'm not sure if they provide any benefits if the traditional GPOs already being set. Otherwise, I will add all others 👍❤️ Thanks for great contribution.

femdiya commented 3 months ago

I see no problem adding them to the project. And yes, I know that some of keys are provided, we set them earlier in a different path. However, as I mentioned, my contribution only persist on completing this project. And there's no downside of using those codes, so why not?

undergroundwires commented 3 months ago

MDCoreSvc cannot be disabled anyway as a service due to permissions errors, alternative way is added see: https://github.com/undergroundwires/privacy.sexy/issues/385#issuecomment-2260606743, commit b40e46a209b1f025f391b091fe06f0a5bf0cdb9d.

undergroundwires commented 1 month ago

SgrmAgent and SgrmBroker belongs to System Guard. Should they really be disabled as part of Defender? Any justification?

femdiya commented 1 month ago

Does disabling them brick the system or anything? Or any possible outcome?
