title: Change Jenkins from running as windows service to CLI, while remaining the jobs
body: <p>I have a Jenkins installation which runs as a Windows Service under a specific user. Now, we want to be able to access the UI for system tests, which is not allowed with this user. </p>
  
  <p>My idea was to start Jenkins from the command line (using Jenkins.war) such that it is run with allowance of desktop interaction, while still using the specific user. </p>
  
  <p>However, when I run this I get an 'empty' Jenkins, so nothing is configured (no settings, no jobs). Do I have to do something special to run Jenkins from the command line retaining the settings and jobs once it has been installed as a service?</p>
