The themes service is responsible for Visual Styles.
Using Microsoft� Windows� XP, you can now define the visual style or appearance of controls and
windows from simple colors to textures and shapes. You can control each defined part of a control
as well as each part of the non-client (frame and caption) area of a window. The user can then use
the Appearance tab in the Windows Control Panel to switch between the classic visual style and other
available styles. A visual style is included with the Windows XP release. Using helper libraries and
application programming interfaces (APIs), you can incorporate the Windows XP visual style into your
application with few code changes. For more information, see the Platform SDK documentation in the
MSDN Library. If your memory conscious and do not care about the "new" XP look, disable this service
to save RAM. I have observed between 4 MB to 12 MB of RAM used for the new themes.
