From the developer:
AltSwitch is an advanced replacement for the standard Windows Alt+Tab task switcher. AltSwitch lets easily navigate between tasks running on your computer using keyboard and/or mouse, mouse wheel supported as well. For each task small preview image is displayed, size of the preview image is adjustable. Task preview includes all task windows, even those that are floating palettes. Previews are caching for faster drawing.
