Default Behavior

The File Information FS MiniFilter service is a file system driver. In Windows 8 it is being loaded by Boot Loader before Kernel initialization. If File Information FS MiniFilter 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 FileInfo service hasn't been started.


File Information FS MiniFilter can't start, if the FltMgr service is disabled or not available.

If File Information FS MiniFilter is disabled, the Superfetch service will not be started and initialized.
