If the Shutdown patch installed but not working correctly,
The Fast Shutdown registry key may be enabled.
The Microsoft System Configuration utility includes an option to disable Fast Shutdown. If this option is unchecked in Windows 98 Second Edition, your system may reboot instead of shutting down.
To resolve this issue, backup the registry and/or export the following keys:
go to Start>Run, type regedit. Navigate to:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Shutdown
Right-click on the FastReboot entry, choose modify and type in the number 0.
NOTE: When you apply the Windows 98 Second Edition Shutdown Supplement, which addresses shutdown issues, the Disable Fast Shutdown option is no longer listed on the Advanced tab in Msconfig.
