Microsoft has released a free set of tools and programs for Windows XP that perform a variety of functions. Some of the programs include an addition to the Alt-Tab switching that shows you a preview of the selected window, a graphing calculator, a magnifier, and a photo album generator. I can’t put a link directly to them, so go to Microsoft and search for Windows XP power toys. (There is also a different set of power toys for Win 98 and ME)
