Or go to the start menu, select the control panel, and find the display settings. In windows Vista they hid it under Personalization, in XP I think it said Display, in Windows 7, I have no idea. But if you can find it you can change the resolution of your entire screen. The numbers there (example: 800 X 600) represent the number of pixels displayed on the screen, so chosing higher numbers gives you more pixels per square inch and thus you see more "stuff".
