Easy Computer Basics, Windows 7 Edition

You can change the size of most windows by dragging any edge of the window with your mouse. If you drag either side of the window, you resize the width. If you drag the top or bottom edge, you resize the height. And if you drag a corner, you resize the width and height at the same time.

Position the cursor over the edge of the window.

Click and drag the edge of the window to a new position.
