Default Behavior
Microsoft Passport is a Win32 service. In Windows 11 it starts only if the user, an application or another service starts it. When the Microsoft Passport service is started, it logs on as LocalSystem and running in a shared process of svchost.exe. If Microsoft Passport fails to start, the failure details will be recorded into Event Log. Then Windows 11 should boot up and notify the user about the NgcSvc service startup failure.
Dependencies
Microsoft Passport cannot be started, if the Remote Procedure Call (RPC) service won't start.

3. Close the command window and restart the computer.
The NgcSvc service is using the ngcsvc.dll file that is located in the C:\Windows\system32 directory. If the file is removed or corrupted, read this article to restore its original version from Windows 11 installation media.
