OracleOraDb11g_home1TNSListener Service On Local Computer Started And Then Stopped

While doing some testing of Oracle on a Windows 7 computer I stopped the TNS Listener service also known as OracleOraDb11g_home1TNSListener. The problem is when I attempted to restart the service it would not start. While testing various other things I had made numerous changes so I started looking into what might cause the issue and was pretty confident that the $ORACLE_HOME variable I set within the Windows Environment Variables was probably the culprit. Below I describe more details about the error as well as how I resolved the TNS Listener not being able to start.
