Script to add Regkey Exception to Windows Defender

Question

If I want some kind of script to add an exclusion to Windows file defender, I can do something along these lines by saving the following text as a .bat file and running it:

powershell -inputformat none -outputformat none -NonInteractive -Command Add-MpPreference -ExclusionPath "mypath"

But what if I want to add, specifically, a registry entry exception to Windows defender in a similar manner, how would I acheive that? Is it even possible to add a registry entry as an exception to Windows defender?

Answer 1

Not really an answer, but I do it through the registry here is the info:

File and folder exclusions are stored in the registry key below.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender\Exclusions\Paths

File type exclusions are stored in the registry key below.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender\Exclusions\Extensions

Process exclusions are stored in the registry key below.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender\Exclusions\Processes
