As we all knew, Windows by default don’t support third party theme. Windows 7 is no difference. If we need to use third party theme then we should patch following 3 files.

1. uxtheme.dll
2. themeui.dll
3. themeservice.dll

Fortunately, we don’t need to be a techie to patch it. There is a software which can easily do this job for us.

Universal Theme Patcher is an excellent UxTheme Patcher which supports Windows XP SP2/SP3, Server 2003, Vista SP1/SP2, Server 2008 and Windows 7. It can be used in both 32-bit (x86) and 64-bit (x64) systems.

Just download the package and follow onscreen instructions. After installing it, you need to restart your system.

After completing all task, you need to copy the .theme file and its theme folder to “%windir%ResourcesThemes” folder (where %windir% means “Windows” directory present in system drive where Windows 7 is installed. Most probably C: drive). Now double-click on .theme file and it’ll apply the theme or you can apply it using Desktop Personalization window.
