This was a new feature added to Windows 7. You can dock images onto three different spots on the screen and they will resize: You can dock the window to the top so it will maximize fully or you can dock them left or right to the screen to make them tile vertically in the middle of the screen.
To do this just grab a window and move it all the way to the top/left/right and let the mouse go again. Making working a lot easier and faster!

I’m pretty much impressed with the stability of Windows 7. It is better than windows Vista which hogs my memory and cpu.:“
Even though Windows 7 is tons more better I never had problems with Vista either. It always depends on the user.
