The Windows 98 Second Edition Shutdown Supplement addresses shutdown issues on systems with hardware/software configurations specific to Windows 98 Second Edition. Installing this update will resolve such issues as computers restarting when "Shut down" is selected and computers not responding during shutdown.

Microsoft recommends following the troubleshooting steps outlined in the Microsoft Knowledge Base Article How to Troubleshoot Windows 98 Second Edition Shutdown Problems. (This site is in English.) If, after following the steps outlined in this article, the system continues to exhibit shutdown problems, then Microsoft suggests applying this update.

Some users have tried to address shutdown issues by replacing the Windows 98 Second Edition version of CONFIGMG.VXD with the Windows 98 version. Microsoft strongly recommends that users do not do this. This is an untested scenario that could result in blue screens, ACPI errors and hardware failures. This update will check to see if the appropriate version of CONFIGMG.VXD is installed on the system and replace any older versions with the Windows 98 Second Edition version.
