Default Behavior

The File System Dependency Minifilter service is a file system driver. In Windows 8 it will not be started until the user starts it. If File System Dependency Minifilter fails to load or initialize, the error details should be automatically logged. Then Windows 8 is restarting the PC and attempting to use the Last Known Good configuration. If the Last Known Good configuration isn't working properly, Windows 8 startup ends with a Stop error. If you disable the FsDepends service, Windows 8 will fail to start.


File System Dependency Minifilter can't start, if the FltMgr service is disabled or not available.

Restore Default Startup Configuration for File System Dependency Minifilter

1. Select your Windows 8 edition and update pack, and then click Download.

2. Save the Win8_FsDepends_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

4. Restart the computer.

The FsDepends service is using the FsDepends.sys file that is located in the %WinDir%\System32\drivers folder. If the file is corrupted or deleted, you can put it back in there.
