Close All Windows is a software that allows you to close all applications running on your desktop with a single click. It is very ideal if you would like to close the windows of a chat or a game on your screen when your boss is behind your back. Close All Windows can close any type of application regardless of the number of windows open on your desktop. As it is a portable software, you just need to extract the executable file and to create a shortcut on the desktop. Thus, a click on that icon is enough to close the windows. In addition, you can opt for the command line.
