Registry change to change to default right click
The best solution is to open the registry editor, navigate to \HKEY_CURRENT_USER\Control Panel\Desktop and create three strings (if they don't already exist). Create AutoEndTasks and set it to 1, create WaitToKillAppTimeOut and set it to 2000. Finally, create HungAppTimeOut and set that to 2000 also. These automatically force-close any open apps after a 2000-millisecond (2 second) delay (shorter delays could be problematic because it wouldn't give apps that are closing time to close themselves).
