I followed those suggestions because i too have a pretty slow Dell with Windows Home XP2.
Additionally, I was thinking it might speed up the challenges I have been having with being able to click on "delete" and have it work in a reasonable amount of time.
Is this something to do with the mouse or what??? I have tried to do repairs from the add/remove in the control panel and that hasn't improved it either.
I guess it isn't the end of the world or anything but it is certainly annoying.
Thank you for any suggestions.
