Keyboard shortcut for switching windows in Vista

We can use Alt-Tab to switch the windows in the old fashion i.e the way we used to do it in Windows XP. To see the windows switch in 3D use Windows - Tab key combination. Hold Windows key pressed and then keep on pressing the Tab key. You can see the windows moving to the front one by one in 3D. When you see the desired window in the front position stop pressing tab and release Windows key. This one will become your active window now.
