Windows XP/Changing the Look

The Properties Dialog
You can change the basic colors of the title bars and windows. Right-click an empty area of the desktop and choose 'Properties'. A dialog will appear with several tabs. Choose the 'Appearance' tab. You will see a preview of your current theme. Clicking on areas of the preview will let you change the colors, fonts and sizes.

Changing the Title Bar
Click an active Title Bar on the preview (Light/Dark blue by default). You will be presented with controls that let you change the colors, change the font and font color, whether the font is bold of italic and the overall size. Customize these settings until you have a theme you like, and click 'Apply'. Clicking other areas of the preview change other settings - just experiment!
