how to divide your screen in half
If, specifically, you'd like to have two application windows tiled on your screen, so each is occupying half the screen, one on the left and one on the right, here's how you can use the new Windows 7 Aero Snap (Docking) feature to get two of them side by side, left and right: 1. Open the first application.. Now move your mouse to the title bar at the top of the window, click the mouse and drag that window to the left edge of the screen. Keep dragging until the mouse reaches the edge of the screen and you'll see the outline of the window jump out to the center of the screen.
