This issue may occur if the version of an affected component that is installed on a computer is later than the version that the service pack is designed to update.

To resolve this issue, install software updates for the affected components. To do this, use Microsoft Baseline Security Analyzer (MBSA) to centrally scan the computer for common security misconfigurations and to generate a security report for the scanned computer. MBSA uses the Mssecure.xml file to determine which security updates are applied to a computer.

Note The Mssecure.xml file is continuously updated by Microsoft.

MBSA scans for files in each update package and for the versions and checksums of these files. MBSA also scans registry keys that were applied by the update installation package and for information about which updates supersede other updates. Finally, MBSA scans for any relevant Microsoft Knowledge Base articles. For more information about MBSA, click the following article numbers to view the articles in the Microsoft Knowledge Base:

This behavior is by design.
