Default Behavior

Remote Desktop Services UserMode Port Redirector is a Win32 service. In Windows 7 it won't be started if the user doesn't start it. When the Remote Desktop Services UserMode Port Redirector is started, it is running as localSystem in a shared process of svchost.exe. Other system components, such as drivers and services, may run in the same process. If Remote Desktop Services UserMode Port Redirector fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the UmRdpService service is not running because of the error.
