One of the biggest changes for interface of Microsoft Windows Vista is the underlying icon file format support which we can’t notice by looking at Microsoft Windows Vista screenshots. According to rw-designer.com website, the icon images of windows vista may be stored as PNGs instead of traditional .ICO file formats. Because of the compression technology of PNG file format, the size of an icon is reduced but the quality of the icon still remains the same.

This PNG file format support feature is not available in Windows XP. Hence, this feature will ease designers in creating quality icons and might increase creativity of icon designers.
