Microsoft Security Advisory (927891)Fix for Windows Installer

Microsoft Security Advisory (927891)Fix for Windows Installer
Published: May 22, 2007
Today we are announcing the availability of an update that does not address a security vulnerability, but is a high priority for customers in keeping their systems updated. The update addresses the following issue:

Your system may appear to become unresponsive when Windows Update or Microsoft Update is scanning for updates that use Windows installer, and you may notice that the CPU usage for the svchost process is showing 100%.

When you try to install an update from Windows Update or from Microsoft Update, you experience the following symptoms:

• Your system may appear to become unresponsive when Windows Update or Microsoft Update is scanning for updates that use Windows Installer.

• You receive an access violation error in svchost.exe. This access violation stops the Server service and the Workstation service.

• A memory leak occurs when Windows Update or Microsoft Update is scanning for updates that use Windows Installer.

• Windows Update or Microsoft Update scans take a very long time, sometimes hours, to complete.


We encourage Windows customers to review and install this update. This update will be offered automatically through Automatic Updates. For more information about this issue, including download links for the available non-security update, please review Microsoft Knowledge Base Article 927891.

Please note that this update is the first part of a two-part fix that is the comprehensive solution to the problem. In June, another update will involve the Windows Update client. The update for the Windows Update client will also be automatically offered through Automatic Updates.
