How to implement Remember my Id in this computer?

[Amar More]

hello,
I am implementing messenger in java. I want to proivde the
facility of remembering the id and password on the local machine.
Since I am a new user, I don't know where these id and passwords
are saved in case of Windows operating system.
Can anyone tell me whrere those entries are saved, and general
idea of how to implement that?
Eagerly waiting for your reply.

Ask the user for the id/password, then store it in a
sub-directory of 'user.home'.
