Don't know where it is in Vista, but you can try changing the display resolution to "less" which will spread everything out larger (with less resolution). In Windows XP, you can go to the desktop screen with all the icons, right click the mouse to get a drop down menu, click on "properties" then click on "settings" then slide the slider at bottom left where it says "screen resolution" to the left -less- side. Hit "apply" and it will change.
