I am pretty sure that sometimes while you were working on the computer, you reached a point when all those open windows did more damage than help. Sure, you could start analyzing which one you actually need and which not and close them separately, but this would take a lot of time. For windows opened by Windows explorer, you can press the Shift key and then click on the close button to immediately close them but what can you do about windows opened by third party software?
Well, you would have to install an application like Close All which is able to close open windows with a single click no matter what program opened them in Windows 8. The idea behind Close All application for Windows 8 is pretty simple.
To close all open windows with a single click, Close All application does not require a lot of system resources. It works similar to the way that Windows 8 closes all open windows when you reboot your computer. What this means is that Close All app will send a close message to all open windows that you have opened in Windows 8, once you click on the executable file for the application.
You can find the Close All icon inside the directory where the application is located but to save you some time, you can create a shortcut that can be placed on your desktop or pinned to the taskbar, for a faster access.
The developer of Close All application for Windows 8 allows you to use a custom hotkey to close all open windows at once. To do so, you will have to open the properties of the shortcut previously created and then set the desired hotkey to close the open windows.
If you want to use Close All to close all open windows with just a click, you should know that the application works on Windows Vista, 7 and 8.
