No, it's the local group with the RID 513, which exists on *all*
machines, but is invisible, unless you call NetUserEnum, which
enumerates it, or you call NetUserGetInfo with the localized name.
This group is called "None" in the english OS versions, "Kein" in
the german version, "Aucun" in the french version, etc. All local
users accounts have this group invariably set as their primary group.
For some reason Microsoft decided ages ago, that this group does
not show up in the GUI, and that it's not possible to change the primary
group outside of domains. Why that is, I have no idea.
