VistaGlazz is an application that can easily modify your Windows Vista installation to use custom styles and modify your Aero style to use the Glass effect on maximized windows.The new Aero interface relies on your GPU for a new look with customizable colors and transparency.Unfortunatly as in Windows XP, custom styles are not supported by the system. Programs like WindowBlinds offer a workaround but degrade performance.
The new Desktop Windows Manager in Windows Vista only allows patch system visual styles. Creative minds on sites like DeviantArt create cursors, icons, wallpapers and themes. After using it you can now use custom styles as well.
