Glad you are getting there jrodefeld,

Did you change all 5 parts of the folder icon in the imageres.dll 3,4,5,6,162 in both System32 and SystemWOW64. It does sometimes take a while for them all to take, Rebuild the icon cache again and also delete thumbnails see if you can force them to take.

There are some folder icons in Shell32 as well but you shouldn't have to change them for this to work (I do but that's my OCD) but you could try that also.
