I have always had my C:/Temp in my include list, but it seems that was getting cleaned by CCleaner itself but no because it was in that list.
I realized this today cause I tried to clean only my personalized folders and files (btw the translation to Spanish is wrong, it must say "Carpetas y Archivos Personalizados") by right clicking on it and neither ?Analyze? nor ?Clean? option did nothing but my C:/Temp folder is full of things!
