Default Behavior
The FltMgr service is a file system driver. If FltMgr fails to load or initialize, the error is logged and the computer attempts to restart, using the Last Known Good configuration. If the Last Known Good configuration fails, Windows 8 startup also fails, and the boot process halts with a Stop error. If you disable this service, Windows 8 will fail to start. Do NOT change this service startup configuration if your computer is working.
