You can change the appearance of the bars that surround all of your windows. Click on the Start button and point to 'Settings' then click on 'ControlPanel'. Double-click on the 'Display' icon then click on the 'Appearance' tab. In the 'Items' drop-down box, select 'Active Title Bar' then increase or decrease the width using the Size field. Do the same for Inactive Title Bar, Scrollbar items, and Active and Inactive Window Border.
