I recently reinstalled widows XP Professional on my desk top. Now when I start the computer I get a blackscreen message asking weather I want to use Windows XP Professional or Windows XP Professional set up to start my computer. If I chose XP Professional the computer boots normally, if I chose the setup it goes to a blue screen installation window. If I f3 quit out of that window I need to reboot. How can I remove those setup files without having to reinstall the whole system again as it takes several hours with all of the servicepack updates you have to go through?
