You browse through My Computer or Network Neighborhood leaving lots of windows open on the desktop. Then you close them one by one by click on the close windows button over and over and over. It can be a pain. You don't have to close them one by one. The next time you have a set of either My Computer or Network Neighborhood folders open on your desktop and you want to close them all at once, hold down the Shift key when you click on the close button ( X ) and poof!, they all close.
