The Diagnostic Policy Service enables problem detection, troubleshooting and resolution for Windows components. If this service is stopped, diagnostics will no longer function. If this service is disabled, any services that explicitly depend on it will fail to start.

Diagnostic Policy Service logs on as NT AUTHORITY\LocalService and runs in a shared process of svchost.exe. If Diagnostic Policy Service fails to start, the error is recorded into the Event Log. Windows Vista startup proceeds, but a message box is displayed informing you that the DPS service has failed to start.
