* Tunes Unusual Parent Process for cmd.exe rule to exclude oobe activity
When dllhost.exe is called with the "/Processid:{CA8C87C1-929D-45BA-94DB-EF8E6CB346AD}" argument it is creating an "OOBE Elevated Object Server" as per https://strontic.github.io/xcyclopedia/library/clsid_ca8c87c1-929d-45ba-94db-ef8e6cb346ad.html
Out of the box experience is part of the Windows autopilot and therefore should be legitimate behaviour.
