What Is Diagnostic Policy Service

Diagnostic Policy Service (DPS) is an essential service installed by default in your Windows. This service aims to detect and troubleshoot the potential problems for the components of your Windows. It will initiate automatic corrective action or log the appropriate diagnostic information for the cause analysis of the problems, and then notify the user of the potential problem.

Commonly, this service runs automatically with your system in the shared process of svchost.exe (Service Host) to keep finding issues for the components. If Diagnostic Policy Service is not running, you will be unable to know the causes of issues in your system.
