When I work, I don't usually try Alt + Tab keys to switch between the various programs and applications running on the Windows PC. I'm more of a clicking person but my colelague loves it. Tho' I do use the Ctrl-C (copy) and Ctrl-V (paste) keys at least a few thousand times a day. If you are looking for a cool Task Switcher For Windows XP that shows thumbnails of the applications you are switching between, then see below.
Propellerhead has found a way and it’s called Taskswitch a free add-on from Microsoft. In addition to the normal icon view it also generates a preview or thumbnail of the applications you are switching between. It’s part of the Powertoys suite (which includes the most excellent Tweak UI -- there's more about it on the BootLog website).
