Is there any way to augment this behavior? >=20 > Mounting the volume "noacl" doesn't help? Orphaned SIDs shouldn't happen. Disabling accounts, ok, but removing them? I don't know. So the question is, if there's no account with these SIDs anymore, why aren't these SIDs removed from the ACLs? It's not only Cygwin. These SIDs also unnecessarily slow down each single access check of the OS.
