Windows 7 is known for its beautiful and easy to use interface. And to adds to it beauty.
We have some hidden themes in windows 7, and to access them follow these simple steps.
1. In the search box in the Start menu, type C:\Windows\Globalization\MCT\ and press Enter. (Note: If Windows 7 is installed in a drive other than C:, use that letter instead.)
2. Windows Explorer will launch and show you a list of subfolders under C:\Windows\Globalization\MCT: MCT-AU, MCT-CA, MCT-GB, MCT-US, and MCT-ZA. Each subfolder has wallpapers for a specific country: AU for Australia, CA for Canada, GB for Great Britain, US for the United States, and ZA for South Africa.
For any of the countries whose wallpaper and themes you want to use, go into its Theme folder, for example, C:\Windows\Globalization\MCT\MCT-ZA\Theme. Double-click the theme you see there (for example ZA).
3. This will automatically install a shortcut to the theme and wallpapers in the Personalization section of Control Panel also
You can now use them as you would any other theme or background, by right-clicking the desktop, choosing Personalize, and choosing a background or theme. They will be listed in their own section.
