Simply copy mct-us files from the five folders Mct-au, Mct-ca, MCT-GB, Mct-za, *.theme, and so on in the "\windows\globalization\mct\" directory to \windows\resources\ Themes\ path, you can then find the figure "installed Themes" in the "Personalization" window, where you directly choose to enable the theme effects of the appropriate country (see Figure 1).

In addition, we can name our personalized theme, not just the blunt "unsaved Theme". Right-click the theme icon under the My Themes category, choose Save Theme from the shortcut menu, and then manually enter a name for the new topic, as shown in Figure 2, isn't it interesting? For a topic that is not currently enabled under the My Themes category, you can right-click to select Delete Theme to delete.

If you are using Windows 7 on a portable computer, you can also find a checkbox named "When using Battery Power,pause", which is called "when using" and "slide show to save power", and when you check it, Automatically suspend automatic wallpaper switching, so that can maximize the energy savings, interested friends can try.
