SmallWindows is an Expose clone for Windows. While Windows 7 already has the Alt+Tab, Win+Tab & Desktop Peek features which help you do something similar, SmallWindows brings in focus all the windows at the same time on your desktop when you move the cursor to a hot zone.
Exposé allows a user to quickly locate an open window, or to hide all windows and show the desktop without the need to click through many windows to find a specific target or scale all windows down so you can get an overview of all of them.
SmallWindows attempts to do something similar to what the Expose feature does in Mac.
I opened a couple of windows on my Windows 7 x86 desktop and then moved my cursor to the designated top right corner. SmallWindows scaled-down and displayed all the overlapped windows neatly on the desktop which enabled me to view all and select one.
