Default Behavior
Diagnostic Policy Service is a Win32 service. In Windows 7 it is starting automatically on the operating system startup. Then the Diagnostic Policy Service is running as NT AUTHORITY\LocalService in a shared process of svchost.exe. Other system components, such as drivers and services, may run in the same process. If Diagnostic Policy Service 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 DPS service is not running because of the error.
