Windows install/uninstall as a "service"

When I did the windows install (NOT as a windows service) but as a task to be manually started and stopped, it did not creat a DATA directory, nor did it create a postgresql.conf file.
I even used windows explorer search to confirm that no such file exists.  I did the uninstall and then reinstalled several times, to see if there was any different choice I could make.  My next step would be to configure it as a Windows service.  I am just concerned whether the uninstall of such a windows service would be a clean uninstall.  I would appreciate any advice on how to get this postgresql windows install working on my Dell with XP Professional OS.

 

I feel that IF I could achieve an install which actually creates a DATA folder, and a posgresql.conf file, that I could then attempt to add the listening command.

 

Thanks in advance for any advice or suggestions.
