For an OS like windows 7 which groups all of your stuff it would have been a useful feature if you right click on the taskbar and select ‘close all open windows’ or something like that. Then again, something like that may be really useless if you close all your windows only when you have to turn your computer off and you don’t keep it on 365 days ! In any case some one took the pain to write a small code for some purpose.
You can pin it on taskbar in your Windows OS.
