The "tomcat6w.exe" and "tomcat6.exe" programs are actually instances of the "Apache 
Commons Daemon" software.

The main project page, which explains very well the point of it, is here :

The Windows version documentation is here :

and "tomcat6w.exe" is really a renamed version of "prunmgr".

In short :
if you have installed 3 instances of Tomcat as Windows services, you had to give them 3 
different "service names".
Supposing that one of them is "tomcatA", just invoke tomcat6w as follows :

c:\tomcatA\bin> tomcat6w.exe //ES//tomcatA
and it will show the Registry parameters corresponding to that instance.
