So, the issue is how to have the server log admin in automatically after a reboot, then start the Aware IM Control Panel and then log the admin out leaving the CP running as admin.
This article was the saviour.
Works perfectly. Only change I needed to make was insert a 1 minute delay before the log out task so that Tomcat has an opportunity to load.

This works EXACTLY like I needed and solved the User Defined Document using an Excel template issue also.
So, no need to run as a Service anymore.
