text: windows xp home edition running very slow with more than one person logged on.? when there is only one person logged on, windows runs fine. when that person sits idle for a while, windows closes their screen and brings back up the master log on screen. when another person logs onto this and there are now two people logged on, windows is extremely sluggish. what would be the cause of this and how would i fix it? try and clean some of the junk off the computer there are plenty of programs out there free that will do it also do a virus scan and spewer/add-wear cleaner they can also be slowing you down and do a trojan clean as well then check your page file and see if its set right too much of it or to little of it can affect how well it will run
