Removing a file association in Windows

[anon_priv]

I have an RDF file on my pc.

It is assoociated with IE, Word, and a PDF reader.

I would like to remove the PDF association (it does not open with this programme).

I can't see a way in Vista of removing the association.

Can I edit the registry?

Thanks.
