Default Behavior

Fax is a Win32 service. In Windows 10 it is starting only if the user, an application or another service starts it. When the Fax service is started, it is running as NT AUTHORITY\NetworkService in its own process of fxssvc.exe. If Fax fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the Fax service has failed to start due to the error.

Dependencies

Fax cannot be started under any conditions, if the following services are disabled, deleted or working improperly:

The Fax service is using the fxssvc.exe file that is located in the %WinDir%\system32 folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 10 installation media.
