Windows Defender reset to default configuration

The script appears to be taken from huntress which only reverts huntress settings.

I'm guessing you're trying to reset options/preferences back to what windows does OOBE?
Of course there's a bunch of HKCU sessions, and some that are HKLM settings....and you're probably not referring to just the Security panel?

Based on some searches I don't think Microsoft has a Defender reset script, let me know if you find one though.

I'm thinking you'd have to query every setting from a virgin install home...and manually make them the same.
Then profile for pro.
Then OS detect, and rewrite each setting appropriately...
Then because notifications are custom HKCU reset all those values for notifications...

Whadda PITA.

I'm not trying to do anything. I was looking at some huntress scripts and thought to my self... "this script seems familiar!!"
Searched here and one look at the script screamed "BS" :)

Off the top of my head, I think it would be very difficult to reset defender to factory defaults. I haven't tried or needed to yet.
