Default Behavior

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.


Windows Container Isolation cannot be started under any conditions, if the FltMgr service is disabled.

Restore Default Startup Configuration for Windows Container Isolation

1. Select your Windows 10 edition and release, and then click Download.

2. Save the Win10_wcifs_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

4. Restart the computer.

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