PeterJ,
Still shows one update available (Security Update for Microsoft Visual Studio 2008 Service Pack 1 XML Editor (KB2251487)) and the attempt to install results in failure. Fixlog.txt is attached. BTW, I realized I exaggerated the problem of leaving KB2251487 in place because I can just hide the update, and then I won't see it during updates. Even so, I would prefer it be gone if possible. But I don't want you to waste your time doing it.
Thanks,
Rod
