Microsoft warns of critical flaws 16716

Which means that the switched out processes for that user are not running. This is not muti-user or multi-tasking. It is called context switching in this case. Which means only one user per session.

Yes it does, and looking at the process list for the user switched out shows the user processes as suspended. OS X is not multi-user in this sense and neither is XP or NT. Again, you'd need a port multiplexer to support multi-user concurrent sessions.

This is old hat argument of yours. There is no multi-user concurrent session support in NT or XP, especially XP Home. On VMS the SYSTEM account runs Authorize to set up user accounts. When multiple users login each user has his own concurrent end space in memory along with delegated priviledges and limits on how that user can ubreastilize his own resources. In a networked setup, obviously, one goes thru a server. The picture changes and isn't the same as a true multi-user scenario. Your use of the term 'multi-user' has been redefined from the older term and should be called something else other than 'multi-user'. I'd call it on OS X as instant user context switching.
