Old-school task switcher

Okay, okay, this won't cure any headaches, but it's just plain cool. By this point, most people know the age-old Alt + Tab keyboard command to quickly switch between open programs (and the desktop).
But did you know the classic Windows XP-style task switcher is still hidden within even the latest versions of Windows?

Just hold one Alt button, press and release the other Alt button (while still holding the first one), 

then start pressing Tab to rotate through software like it's 2001.
