Is there a way to configure the alt-tab display, where it shows you previews of open windows? With Win7, I see previews of open windows instead of program icons. Problem - many open window previews look alike. WLM, Word, task manager, anything with a white background and black text looks so similar that it's not quick and easy to tell what is what. So, having said that, how can I configure it to show icons (like XP did?).
