When I shutdown my computer one taskhost window is staying. It uses some seconds more than I want. Can choose to shut it down imediately by using 'kill process button' but it is kind of annoying. How can I identify wich processes who is causing taskhost to hang? Just want to know if it is a legal windows process. It could be the sound driver, but that is possible to tweak i registry if I find out. Been using tools to try find out like security task manager, but it is very difficult to identify such processes hanging at system shutdown. Not good at reading error messages in windows event system either .
