A Visual Style sets the colors and the style of the Windows Xp graphic interface. A Theme is a pack that includes a visual style, some icons and a desktop wallpaper.
Usually in Windows Xp there are only two visual styles: Classic and Luna. The installation of other themes or visual styles is not allowed by default.
To use visual styles we must modify the file Uxtheme.dll with one specific utility. Like the famous Uxtheme patcher (for exaustive informations please go to this article http://cadmus.deviantart.com/journal/2419017).
After this operation we can freely use both *.msstyle and *.theme files.
The *.theme files must be copied manually in the windows/resources/themes folder, while *.msstyle files must be copied in a subfolder named as the style and placed in the windows/resources/themes folder.
Next we can select the theme in the display/proprieties -> themes, while for the visual styles we can go to appearence submenu.
