There are a lot of add-ons for Windows that offer window management, or shell extensions, or task launching. Many of these look great in the screenshots, but then I try them, and am disappointed. They end up being flaky or slow or just awkward. TaskSwitchXP is not one of these. It is a replacement for the Alt-Tab behavior in Windows for switching among running programs. It provides thumbnails of the applications, and a nicer UI for the icons, and lets me just click on the icon I want when I see it. It does just what I want, in a competent unobtrusive way.
