Task Host Window is an intelligent windows program which pops up when you attempt to Shut Down windows. The reason why it pops up is due to the running processes and programs in the background; when you initiate shutdown or reboot, task host interrupts the process to check if all running programs were closed to avoid data loss, the pop up would also show you which programs were running.
