  • On XP, go to the registry directly: 
    Instances of this class represent updates found in two places in the registry:

     

    • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows  NT\CurrentVersion\Hotfix

    • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Updates

  • On Vista+, the registry doesn't exist any more. Try the WMI Class: Win32_QuickFixEngineering Class http://msdn.microsoft.com/en-us/library/aa394391(VS.85).aspx
