How do you remove Facebook contacts from Windows Live Mail.

PLEASE PLEASE will someone tell me how to remove all my facebook contacts from Windows Live Mail.  The facebook contacts are not even current as one of the contacts has passed away and no longer has a Facebook account.  None of my newish Facebook contacts are on Windows Mail so it can't be a current sync.  I have just about tried everything and nothing works.  Been on to live profile which a lot of people said would work but although I deleted Facebook it made no difference which I guess was not surprising as the facebook contacts on Live Mail is not current.  Does someone know the answer that will work.  I have Windows 7.
