**THIS IS FOR WINXP HOME SP2, I am unsure about XP PRO.**
Actually, you can. **BE VERY CAREFUL HOW YOU DO THIS.** It deals with modifying your registry, so make a backup if you feel unsafe. I believe you will need ADMINISTRATOR privileges. Go to start, the click run and type regedit. Then click the "+" next to HKEY_LOCAL_MACHINE, then the + next to "SOFTWARE" then the + next to "Microsoft" then the + next to "Shared Tools" then the + next to "MSCONFIG" then "startupreg". Here you should see a list of items that are in the box. BE CAREFUL that you do not disable anything required by your drivers and make sure that what you are deleting you won't need to re-enable. REMEMBER, make a back up of your registry just incase! This worked for me, so if anyone else is interested!
