Could you clarify this? As far as I know, Windows NT *is* a single-user
system, period. Citrix (and maybe others?) has/have, as you say,
"grafted" varying degrees of multi-user capability onto it, but stock,
"out of the box" NT (Workstation or Server) is a single-user OS, and I
haven't seen any part of it that claims to be anything else. As such, I
don't see where a "flaw" regarding multi-user-ness would arise.
