ThumbWin!

VistaSwitcher is an elegant and powerful task management utility for Windows OS. Once installed, it replaces the default Windows Alt-Tab dialog with a nice box that shows a list of all running tasks, with their names and preview snapshots, and enables the user to take actions on them using the mouse and keyboard shortcuts. With just one click, you can switch tasks, minimize, maximize, restore the main window, or close the process.

TaskSwitchXP is an advanced task management utility that picks up where the standard Windows Alt+Tab switcher leaves off. It provides the same functionality, and adds visual styles to the dialog and also enhances it by displaying thumbnail preview of the application that will be switched to.

SmartTab, the better Alt-Tab (a Windows Alt-Tab Dialog replacement).

If you are not familiar with the Alt-Tab task switcher in Windows, its a keyboard short-cut (hot-key) to enable fast switching between applications/windows. This feature has been in Windows since Windows 3.0 and is largely unchanged since Windows 95! Alt-Tab Thingy is a replacement to add brand new features to help you switch tasks faster and more efficiently than ever before!
