Microsoft Pluton Service is a kernel driver. In Windows 11 it starts only if the user, an application or another service starts it. If Microsoft Pluton Service fails to start, the failure details will be recorded into Event Log. Then Windows 11 should boot up and notify the user about the Hsp service startup failure.
