Named pipe service trigger provider is a kernel driver. In Windows 11 it starts at Kernel initialization. If Named pipe service trigger provider fails to load, the error will be logged, and Windows 11 will try to restart, using the Last Known Good configuration. This may lead to repeated reboots, when the Last Known Good configuration is estimated as proper, but the service remains unable to run.
