In Windows Vista the window title and icon has been removed in all instances of Windows Explorer. The result is a blank space in the window that just does not look good where the window title normally is placed.
Using a cool free utility called AeroBar you can restore the window titlebar title and icon. To use the utility visit Outils (http://www.psscript.net/utils.htm) and download AeroBar.exe (http://www.psscript.net/AeroBar.exe).
Install is a snap. Just copy the utility to the Start Up folder of your start menu. If you want to also show the folder icons, just rename AeroBar.exe to AeroBarIco.exe.
To disable AeroBar just run the executable again.
