The regpwd stored passwords are stored in the same (Windows standard) 
way as e.g. Dial-in passwords or service account passwords are stored, 
i.e. under:


In Interix in security.h there are setsecret() and getsecret() 
available for storing and retrieving the passwords. There is also a 
man page for these 2 functions.

The tool Cain from may be helpful, too.
