I had to replace a broken hard drive on my HP Pavillion desktop and restore with the recovery CD's. I had lots of problems but finally got it to restore and work but now the XP Automatic Update process is broken. Every time it tries to download and install a patch I get an error message "Some updated could not be installed" and nothing is installed. Most of the patches I can then go in and download and install manually OK but there are a few that will not install that way either. Is there any way to reinstall the XP Automatic Updates software to get this working correctly? I see that others have suggested malware but for me this is not the case because it stopped working immediately after a fresh restore with my recovery CD's. I was able to manually download and install XP Service Pack 3 and most fixes that pop up with the Automatic Updates window.
