The Windows 7 theme allows you to easily change the look of the Windows 7 user interface elements.
Each theme in the previous versions of Windows included only one desktop background option. In Windows 7, a theme can include multiple desktop backgrounds that are displayed sequentially, like a slide show.
Each theme can include the following four elements:
A desktop background image or color
A color that control window frames, Start menu, and the taskbar
Sounds that are associated with specific actions
A screen saver that starts after a period of inactivity
Windows 7 also comes with a set of Aero themes that includes:
Windows 7 (the default)
Themes that include graphic backgrounds, such as Architecture, Characters, Landscapes, Nature, and Scenes.
Themes relevant to different countries.
In addition, Windows 7 includes two basic themes designed for computer systems that don't support Aero graphics, and four high-contrast themes designed for people who need additional help viewing information on the screen.
