I'm trying to find a best solution to multi-user system at home. Basically, I have some education programs for my son but I don't want all the program groups, system files to affect my system. Currently, I have multiple-boot system so one system has all the edu-games while I use my a different system. I use System Commander to do the system switching. There are a few drawbacks. 1) it's a lot to maintain 2 systems. Everytime I rebuild my system, I have to set up another system. 2) I cannot have 2 identical system switchable with System Commander, e.g., 2 Windows SE running. I have to have 1 Win98SE and another Win98 Chinese. It appears to me if I install Win98SE on C:\ and then install Win98SE on D:\ then, it's still one Win98SE since it just switchs the system from C: to D:. If you have 2 different versions, then, they would be recognized as individual systems. I know you can login to Win98SE, Win2000, etc... as different users. From what I see, you get different desktop, favorites, start menu. You still share the same system folder so whatever system junks installed from edu-games, it gonna affect my own login. On Win2000, there is settings folder "All Users" that many programs you install would still show up no matter which username you chooe to logon. Is there a way that each individual user would have more isolated system resources that one won't affect the other. I hate these games that keep installing QuickTime 2.1, 3.0 when my system already got QuickTime 4, or installing something unknow to my working machine.
