Default Behavior

The Fax service is a Win32 program that can be started by the Service Controller and that obeys the service control protocol. In Windows 8 it will not be started until the user starts it. When the Fax service is started, it runs as NT AUTHORITY\NetworkService in its own process of fxssvc.exe. If Fax fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the Fax service hasn't been started.


Fax can't start, if any service from the list below is disabled or not available:

The Fax service is using the fxssvc.exe 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 8 installation media.
