OK a bit of an involved situation here: :)

First off I wanted to add a registry key to make Windows Defender scan for incoming files only. I was going to add this DWORD value to HKLM\Software\Microsoft\Windows Defender\Real-Time Protection:

RealTimeScanDirection = 1

However I couldn't because the permissions likely didn't allow for it. So I changed the owner of the "Real-Time Protection" key from SYSTEM to Administrators (I even tried for my user account which is just the renamed Administrator account). I assigned full control rights to Administrators and "Me".

However I still cannot add the DWORD value.

Now I made myself owner of the entire Windows Defender key thread, and I can change values of other keys. But I can't add or change anything in the Real-Time Protection key.

I'm perplexed. After that, I want to see if there's a way to reset the permissions on the Windows Defender keys (the entire tree).. Any takers?
:)
