title: How to let my application to be running even when Logged off the machine?
body: <p>I have developed a TCP Server. I want my TCP server to be running even when I log off my machine. So clients can connect to it even when my computer is logged off.  I was thinking if I must create a Windows Service to implement this approach, but I am not sure how to do so.</p>
  
  <p>Please tell me how can I let my application to keep working even when my machine is logged off.</p>
