lisp-in-a-box

I have been a programmer for a decade now, but I believe this is the first time I've ever asked a question on a forum. I just can't figure this out and can't find the answer already online. I am trying to turn on CUA mode so that emacs is more bearable for a windows user (normal copy paste functions). I am running Windows 7 and installed emacs through the Lisp In A Box package. I understand that I need to add a line to my .emacs file or init.el file. I'm not sure which, but I can't find either in my Lip In A Box install directory. The emacs package install also did not come with any tutorials
