Now that we have covered the elements that can be part of a theme, let’s take a look at changing the theme. Open the Display Properties dialog box (right-click the desktop and then select Properties).
Make sure the Themes tab is selected. Click the Theme drop-down box (see Figure 3.10) and select a new theme. Depending on the elements that were part of the theme (a style, a color scheme, a sound scheme, mouse pointers, and so on), these elements will be changed.
