Vista - File associations and MIME types

Let's say for example that I have a .zip file that I want to rename to some
other random extension (I'll now call it a .abc file), and I want windows to
handle .abc files just like .zip files, using zipfldr.dll. How can I do this
in Vista? In XP (and all previous Windows from what I remember), when you
went into the list of File Types (which is now under Default Programs), you
could add a new file extension, then select a MIME type to treat the file as.
All Vista seems to let you do is select a program.

(Please don't respond to this post by saying "Just go into Default
Programs... it's easier now". That's all I've been able to find on this
subject so far.)

What I've done for this, is change the extention, then right click and go to
properties.
It lists the type of file and opens with. Here I select change and browse to
the
file I want to use.

Yes, that brings up a list of *programs* that you can choose from. Windows
handles zip files with zipfldr.dll, a dynamic link library that can't be
called as a program. I guess my real question is how do I call zipfldr.dll
for any other file type that I want. It was easy to do under previous
versions of Windows, but there seems to be no way to do it now.
