This program will patch your theme engine files so you can use any 3rd party visual style. Since Windows XP was released, there are countless 3rd-party visual styles released by many skinners in order to improve user's experiences and eye candy. To use non-certified visual style is disallowed by Microsoft's certificate protection so you need to bypass certification verification in uxtheme.dll.
