Hi, Michael.

I only looked at this one so far, and I think it could be improved by having a
map of kernel32 class ids to ntdll class ids instead of having it unrolled like
this. Also I don't think we need to forward everything to ntdll, a way
GetFileInformationByHandleEx() does it is better in my opinion.

Do you think you can work on it to improve and send in?
