From the PC Mag I talked about in my previous post, I learned about a way to make Windows XP perform better. I know Tim did the same thing to his computers recently, but I did it on my own and cannot believe the difference.
You will lose the 'XP Styles' etc, but it is well worth it if you crank on computers all day...
Right-click My Computer -> Properties -> Advanced Tab -> Performance Settings -> pick 'Adjust for best performance'
***then reboot and WOW! The speed of doing everything increased dramatically for me.
