Windows Font Cache Service is a Win32 service. In Windows 10 it is starting automatically when the operating system starts. Then the Windows Font Cache Service is running as NT AUTHORITY\LocalService in a shared process of svchost.exe along with other services. If Windows Font Cache 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 FontCache service has failed to start due to the error.
