title: How do I change a Windows Service's startup type in .NET (post-install)?
body: <p>I have a program that installs a service, and I'd like to be able to give the user the option later on to change the startup type to "Automatic".</p>
  
  <p>The OS is XP - if it makes any difference (Windows APIs?).</p>
  
  <p>How can I do this in .NET? C# if possible! :)</p>
