Im using Windows Live Messenger 2009  and i was just wundering were  the Contact data is stored on my computer(vista Bussiness)

On Windows live messenger 8.5  , it was stored  in app data-microsoft-messenger
                                                                                               - Contacts

I just want to know weather this is the same and if ther is more places my Email address's information is stored.

Check these two:
%userprofile%\contacts
%localappdata%\Microsoft\Windows Live Contacts
