Here is the link for the Ophcrack CD for Windows XP and Windows Vista

http://ophcrack.sourceforge.net/

Yeah i tested this one, its working i.e For windows xp successfully got the admin password (upto 14 charcters only)

and Vista is for only 6 characters there in the website and the cd readme file you can see this information.

Very happy when i check and found the password. Any other more information you people got .
