Once you have installed Oracle database and rebooted the system you can go to a command line window and type the following:
C:\Users\hecperez>LSNRCTL SERVICES
The response should look like this:
LSNRCTL for 32-bit Windows: Version 11.2.0.2.0 - Production on 20-FEB-2014 10:23:51 Copyright (c) 1991, 2010, Oracle. All rights reserved.

This was useful for me when I was trying to connect to an ORCL SID and I was getting an error, I just executed this command and discovered the SID was not in my local database so I just used another available one.
