Close All Windows (or CloseAll) is a small enhancement utility for Windows that flashes a ‘close’ signal to all running applications and then ceases. What can be easier than a task list with check boxes and OK button? You can select multiple apps by clicking them in the list and then click the OK button to close selected apps or use individual close buttons to close apps one by one. CloseAll is an ultimate task management tool: you can choose different sorting and grouping options, customize the size of icons, search for apps by typing any part of their window title or app name.
