Service Host Diagnostic Policy Service is a crucial service policy that is installed by default in all Windows 11/100 systems. The function of this service is to detect and troubleshoot the issues on Windows 11/10 system components. It initiates the corrective action automatically and notifies the user about the potential issue. It also creates a log for appropriate diagnostic information for the cause of the issues.
The Diagnostic Policy Service runs automatically in all Windows 11/10 PCs under the shared Service Host process (svchost.exe). If this process does not run, you will not be able to know the cause of your system errors. You can find this process running in the Task Manager, which you can launch by right-clicking on the Taskbar. Now, scroll down in the “Processes” tab to view the process running in the background.
