Default Behavior
Background Intelligent Transfer Service is a Win32 service. In Windows 7 it is starting automatically after the operating system is started. Then the Background Intelligent Transfer Service 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.
