Try this registry hack from faq item http://www.thethin.net/faqs2.cfm?id=125&category=2 Enable AutoEnd Tasks. If you get a WOWEXEC error when shutting down or executing a program this edit is for you. This parameter tells any task that will not respond to the shutdown notice to end. "HKEY_USER\.DEFAULT\Control Panel\Desktop" Add Value: AutoEndTasks REG_SZ: 1 An additional value: WaitToKillAppTimeout REG_SZ: 20000 The default of 20000 milliseconds (20 Seconds) can be increased if the user process does not end by this time, AutoEndsTasks is executed.
