Windows 7 shows a lot of new features on the PDC 2008, but there's a very interesting and practical one that is somehow completely ignored, and it's called Aero Shake.
What's the use of this aero shake? Simply put, if you have a lot of windows piled up on your desktop, but just want to use one of them, and let the other are minimized, at this time you can put the cursor on the title bar to keep the window, hold the left mouse button around two, the other window on the swish "disappeared", and then shaking two, and back, and maintain the previous layout.
In fact, the use of it is not so complicated, look at the video to know.
In addition, Windows 7 introduces a display mode named "Aero Peek", which allows the selected window to appear normally, and other windows to be transparent, leaving only a translucent border. The Aero shake looks better.
