title: impersonation for windows service using config file
body: <p>Currently to run windowsservice as a fixed user we set the logon properties on the windows service (where we specify the username and password to run as).</p>
  
  <p>but iam willing to have this feature of running the windows service as a fixed user 
  as impersonation in web application mentioned in the config file.</p>
  
  <p>kindly throw your thoughts on this , is it a workable approach
  easy way to implement this.</p>
