Default Behavior
Windows Perception Service is a Win32 service. In Windows 10 it is starting only if the user, an application or another service starts it. When the Windows Perception Service is started, it is running as NT AUTHORITY\LocalService in its own process of spectrum.exe. If Windows Perception Service fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the spectrum service has failed to start due to the error.
Dependencies
Windows Perception Service cannot be started under any conditions, if the Remote Procedure Call (RPC) service is disabled.
