How can you make each user in an XP system look as if they were on a network as separate computers?
Give each user their own computer on the LAN.
Each user should have their own username/password. Any changes a
user makes to the way their desktop looks is JUST for that user. If
user A logs into the PC, and turns the Active Title bars purple,
only user A has to live with purple Active Title bars. User E could
log in and make his/her Active Title bars orange, without affecting
Install and use Microsoft's free VirtualPC virtualisation
program. Each virtualised environment gets its own IP and each user
can run his/her own environment.
