TaskSwitchXP

TaskSwitchXP is a task switcher for Windows XP. This is the same as the one when you hit Alt-Tab to go through your applications and switch between them, except this has a lot more functionality and is a lot better looking than the one that does come with Windows.
Only for Windows XP and 2003.
Funny how another open-source product whips the standard things that come on Windows.
