What is the meaning of this entry in the event viewer:

Event ID: 4

File System Filter 'wcifs' (Version 10.0, ?2016?-?09?-?15T11:42:03.000000000Z) failed to attach to volume '\Device\HarddiskVolumeShadowCopy6'.  The filter returned a non-standard final status of 0xC000000D.  This filter and/or its supporting applications should handle this condition.  If this condition persists, contact the vendor.

How do you troubleshoot this problem?

Hi,

"wcifs" means Windows Container Isolation file system, Windows Container Isolation is a file system driver. In Windows 10 it is starting automatically when the operating system starts. If Windows Container Isolation fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the wcifs service has failed to start due to the error.
