Diagnostic Policy Service (DPS) enables problem detection, troubleshooting, and resolution for components in the Windows operating system. If this service is stopped, diagnostics cannot function. Diagnostic Policy Service supports the Network Diagnostic Framework that is used to troubleshoot network connectivity issues.

This service is installed by default and its startup type is Automatic. When Diagnostic Policy Service is started in its default configuration, it logs by on using the Local Service account.

This service is not dependent on any other system service, nor is any service dependent on it.
