When installed in Standard mode, the gateway runs as a Windows service, which is why you need to run the installation as an administrator. This service is called the On-premises data gateway service. Once installed, this service is set to automatically start when the computer is rebooted. This Windows service continues to run even if you close the gateway administration screen that appears at the end of the installation. If you close the administration application, you can bring the administration screen back up by finding and running the On-premises data gateway in the Windows Start menu.
