@BedCruncher Everything seems to be working with no AV, no FOG Client, and no AutoLogon/CopyProfile. Only problem now is that the administrator account is NOT enabled because there is no “net user administrator /active:yes”, so I need to reintroduce AutoLogon and see if everything breaks again.
EDIT: I also took a snapshot within VirtualBox for my “PreSysprep”, which means I’m not sysprepping the “same” image 5000 times over.
