For example, if the update that is documented in Microsoft Knowledge Base article 911565 (Microsoft Security Bulletin MS06-005) is not applicable, Microsoft Windows Software Update Services may incorrectly display the status as Installed.

Note This issue does not affect security. If an update is installed or required, the status is correctly reported. Only updates that do not apply to the computer may be affected by this issue.

  • You are using a software update program or a detection utility that uses the Windows Update Agent (WUA) API.

Scanning utilities that use the WUA API include the following programs:
  • Windows Server Update Services (WSUS)
  • Microsoft Systems Management Server (SMS) 2003 Inventory Tool for Microsoft Updates (ITMU)
  • Microsoft Baseline Security Analyzer (MBSA)
