Desktop theme overview
A desktop theme is a predefined set of icons, fonts, colors, sounds, and other window elements that give your desktop a unified and distinctive look. You can switch themes, create your own theme by changing a theme and then saving it with a new name, or restore the traditional Windows Classic look as your theme.
If you modify any element of a theme, such as your desktop background or screen saver, it is recommended that you save your changes with a new theme name. If you modify your desktop and don't save your changes with a new name, your changes will be lost if you select a different theme.
Use Display in Control Panel to select or save a theme. The desktop items that are saved with a theme are listed in the table below.
