The *.deskthemepack file format
Starting with Windows 7, Microsoft invented a new theme format - themepack. It was created so all the theme resources would be packed inside a single file and sharing of such themes would be easy. In Windows 8, the file format was revised to deskthemepack, and supported specifying if the window color would be automatically set based on the dominant color of the desktop background. Windows 10 supports both themepack and deskthemepack formats. Technically, themepack and deskthemepack are usually ZIP or CAB archives that contain images, and the corresponding *.theme text file with image names packed into a long text block.
Interested users can directly extract images from such files. This can be useful for Windows 7 users, since the OS doesn't support *.deskthemepack files. The alternative solution for Windows 7 is Deskthemepack Installer, the app that allows to install Windows 10 and Windows 8 themes in Windows 7 with one click.
