I attempted to install SP-2 on a laptop computer. During the installatin, the computer froze. Rebooting resulted in SP-2 being uninstalled and the computer reverting back to it's original configuration- a rather long process. Just to be sure, I ran an XP repair process (not the recovery console repair but the one that can be selected during install) and the computer seems OK. Now, with Autoupdate on, Microsoft is attempting to download and install XP again. I still would like to install the periodic security updates but not SP-2. How can I prevent SP-2 to always appear in Autoupdate?
