Diagnostic Policy Service is a Win32 service. In Windows 8 it is starting automatically during the operating system startup. Then the Diagnostic Policy Service runs as NT AUTHORITY\LocalService in a process of svchost.exe, sharing it with other services. If Diagnostic Policy Service fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the DPS service hasn't been started.
