I experienced problem that applying KB2618444 update always failed. I have asked the question to "Microsoft Answer" at http://answers.microsoft.com/thread/74e2bcf4-6724-4933-968c-28640f8ec7b6. As it still cannot be resolved after some suggestions, the support engineer finally provided a link to me which brought me into this forum for further help. The thread at Microsoft Answer (http://answers.microsoft.com/thread/74e2bcf4-6724-4933-968c-28640f8ec7b6) has captured the details of the issue. Could someone help further to resolve this issue?
