Default Behavior
Hyper-V Guest Service Interface is a Win32 service. In Windows 11 it starts only if the user, an application or another service starts it. When the Hyper-V Guest Service Interface is started, it logs on as LocalSystem and running in a shared process of svchost.exe. If Hyper-V Guest Service Interface fails to start, the failure details will be recorded into Event Log. Then Windows 11 should boot up and notify the user about the vmicguestinterface service startup failure.
