I tried 'python OvirtGuestService.py install' || 'net start OvirtGuestService', it just logged me out and no ip was reported to the engine. However, when I logged as any user on Windows  using 'python OvirtGuestService.py debug', it seemed to be working all fine(ip, application... were reported) .

Someone said that the service must be started under a user, I tried make it started with a user, like Administrator, LOCALSYSTEM, but an error reported.

Do I have other ways to make it run as a service?
