Remove taskbar buttons
One problem with the previous tip is the buttons will gobble up valuable taskbar real estate, but you can reduce the impact of this by removing their text captions. Launch REGEDIT, browse to HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics, add a string called MinWidth, set it to 54, and reboot to see the results.
