Close All definitely works, is complete freeware, is a very small application, and even comes in a 64-bit variety. Very useful for closing all applications on the desktop instantly. Although your stated goal seems to be simply to close stacks, all you have to do is right-click on the stack in the taskbar, and again, "Close all windows".I thought this was an obvious straight forward question. I can't believe MS does not have this feature or a work around implemented for something like this. Can anybody in this forum help/suggest?
