Windows text editor for .conf files

I’m looking for a windows text editor with syntax highlighting for asterisk .conf files.
I’ve been looking around google for a few hours unsuccesfuly so i thought i’d turn here.
I’ve been using sublime text untill recently, so if you know of any plugin or another way to add highlighting for .conf files to it, it would also be a very good solution for me (i tried most available syntax highliting types, but i didn’t find any that work well).

Did you try Notepad++?
