title: Inno Setup Service Log On As
body: <p>Can you advice me how to get "Log On As" parameter of specific windows service?
  I need to re-register service in our upgrade project and it needs to be run under the same account as it was set up originally.
  I've found QueryServiceConfig in advapi32.dll with lpServiceStartName in returned structure but I am not able to make it work from Inno Setup.</p>
