recently stumbled on this really cool freeware app for your PC.
I know almost everybody already upgraded to Windows 7 and enjoys the nice features, of window management.
But Aquasnap will add even more possibilities like dropping windows to corners, top and bottom of your screen. AND it properly supports multiple screens, like dropping a window to the upper left corner of your right screen.
Also clicking on windows+shaking the mouse can either be used to minimize the rest, like default in windows or to be used to make the window transparent. Even more features available in the settings menu.
Have a look at it, pretty useful.
