If you have Windows XP, you'll want to grab this sucker right away. It comes with an updated version of TweakUI, a Graphing Calculator, and several integrated Shell features. Take note: this is an UPDATED version of the original XP PowerToy release. This new package comes with an ISO Burner, Taskbar Audio player, and a Desktop Background Switcher. I'm not sure about any bug fixes. Last I knew, the HTML & CD SlideShow Generators were buggy and would delete images that were processed. Regardless, you MUST uninstall the older PowerToys before installing this new set. Enjoy! (Source: NeoWin)
