If File Information FS MiniFilter fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the FileInfo service has failed to start due to the error.


File Information FS MiniFilter cannot be started under any conditions, if the FltMgr service is disabled.

While File Information FS MiniFilter is stopped, the Superfetch service cannot be launched.
