XP Service Pack 3 user. All of a sudden, automatic updates will not enable in Win. Security Center. My computer did have a bug last week and I had to run a fix which worked on some of the registry files. Since then, I cannot enable the updates. Any clues? I run AVG, spybot and malware bytes.
AutoFix you suggested did not work--nothing happened. I have SP3, not SP2. When following your instructions and finding the SP files and i386 folder, I get a prompt stating "the wuapi.dll on winxp sp3 CD is needed. Is there any way to get the registry files I need or do I need to completely reinstall Win XP?
