I am neither able to shutdown nor run Windows and Microsoft updates. My\ndesktop, which is being run by XP SP2, hangs at the Windows is shutting\ndown screen, and freezes almost immediately when I try to access updates\non Microsoft's site. My Windows update log shows a 8024A000 error, which\nis associated with checking for updates when shutting down, thus\nindicating why neither shutdown nor updates is working. But, I can't\nseem to find a way of solving either problem individually or together.\nI've tried stopping the update service and re-registering the\nassociated files; clearing out temporary internet cache and cookies;\ndisabling my anti-virus software (AVG free); cleaning adware, spyware,\nmalware; using the classic view at startup; and others that I'm not\nrecalling at the moment. I have had the problem before, but was able to\nfix it. This latest dilemma arose yesterday when I tried to download\nMicrosoft updates. I got the site to scan my computer and identify the\nupdates I needed. However, when I tried to download the updates I\nwanted, it froze me out. And that's also when hanging at shutdown\nstarted again. Anyone have thoughts on what I should do?
