Hi Folks – We have investigated reports that the KB973869 (MS09-037) update is re-offered through Automatic Updates and Windows Update on some x64 systems, after it has already been installed. We have identified some limited scenarios where this is occurring with Windows Server 2003 x64, Windows XP x64, and Windows Server 2003 for Itanium-based systems. No systems are left unsecure due to this behavior. A revision to the update detection logic will be published shortly to prevent this update from being re-offered after it has been installed, and to ensure clients accurately describe the updates' installed status. If you have installed this update, you do not need to re-install the revision.
We apologize for this inconvenience,
The MU Team
