Windows Vista has improved the UI and added lots of features like Aero effects when compared to XP. Vista is definitely a great looking OS (we are comparing only the looks here). You can customize Vista just like XP using visual styles. There are lots of styles available based on whether you have/enabled aero effects. So here is a list of seven good looking visual styles (themes) for Windows Vista.
NB: Before installing any theme, please check the instructions provided by the theme author, also check the compatibility of the themes with different versions of Vista. All credit to the author of the theme.
