where is .emacs configuration file

[ccc31807]

Hello,

Brand new to emacs, but a long gime vi user. Just installed
GNU Emacs 23.2.1 (i386-mingw-nt5.1.2600) of 2010-05-08 on G41R2F1
Using Windows XP, SP3.

Two questions:
(1) Where is the emacs configuration file? I have several, and suspect
that it at C:\Documents and Settings\username\.emacs, but the changes
I have made in that particular file don't seem to affect the behavior
of the emacs program.
(2) What simple change can I make in the configuration file as a test
to see if the changes take effect? I tried (print "Hello") but that
doesn't result in any message when I start emacs.

Thanks, CC.
