Symptoms

You use Automatic Updates to scan for updates or to apply updates to any applications that use Microsoft Windows Installer 3.1. After you do this, you experience issues when you use the following update mechanisms:
  • Microsoft Update
  • Windows Server Update Services (WSUS)
  • The Microsoft Baseline Security Analyzer (MBSA) 2.0
  • Microsoft Systems Management Server Inventory Tool for Microsoft Updates (SMS ITMU)
Some applications that use Windows Installer include Microsoft Office 2003, Microsoft Office XP, and Microsoft Windows Defender. These applications experience the following issues:
  • The Svchost.exe process may spike the CPU usage to 100 percent during update detection or update installation. Also, the Svchost.exe process causes the computer to stop responding for various lengths of time.
  • The Svchost.exe process produces an access violation during update detection or update installation. Additionally, you receive the following error message:
    SVCHOST.exe Application Error
    The instruction at 0x0745F2780 referenced memory at 0x000000000 the memory could not be read.
  • The Svchost.exe process leaks memory during update detection or update installation.

Resolution

Microsoft provides the following updates to resolve these issues:
  • Update 927891 resolves newly-discovered crashes that occur in the Svchost.exe process. Because of the access violations that update 916089 does not resolve, update 927891 also resolves the reported access violations that occur in the Svchost.exe process.

    Note These secondary access violations were not exposed until after update 916089 was applied. The secondary access violations are not caused by update 916089.

    927891 You receive an access violation error and the system may appear to become unresponsive when you try to install an update from Windows Update or from Microsoft Update

The WSUS version 3.0 client program has been released to help address the following issues:
  • You may experience prolonged high CPU usage when you scan the computer for updates or when you install updates.
  • The computer stops responding (hangs) when you scan the computer for updates or when you install updates.
To resolve these issues, you must install update 927891 and the new WSUS 3.0 client.

Notes
  • To resolve this issue, you must be using version 374 or a later version of the Windows Update Agent.
