Fatal Error Solutions


STOP: 0x000000F5


The filter manager device driver likely has a bug. Most often a filter manager is part of the Anti-virus or a backup software.

This is a fatal Windows error, typically called a Stop message, Bug Check, or more commonly the Blue Screen of Death (BSoD). The system is in a forced reboot state. Any unsaved work is likely lost.

  Sample Screen  

A problem has been detected and Windows has been shut down to prevent damage to your computer.


If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any Windows updates you might need.

If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.

    Select Start, right click Computer and on the drop-down, select Properties.

An unrecoverable failure occurred in the Filter Manager.

After the Stop code will be 4 hex values: {Parameter 1, Parameter 2, Parameter 3, Parameter 4}.

Parameter 1 specifies the cause of the issue.

0x00000066 The minifilter returned FLT_PREOP_SUCCESS_WITH_CALLBACK or FLT_PREOP_SYNCHRONIZE from a preoperation callback, but did not register a corresponding postoperation callback.
0x00000067 An internal object ran out of space, and the system is unable to allocate new space.
0x00000068 Unexpected failure referencing an object.
0x0000006A The file-open or file-create request could not be canceled, because one or more handles have been created for the file.
0x0000006B Invalid BACKPOCKET IRPCTRL state.
0x0000006C Too many nested PageFaults for BACKPOCKETED IRPCTR.
0x0000006D The context structure was dereferenced too many times. This means that the reference count on the Filter Manager's CONTEXT_NODE structure went to zero while it was still attached to its associated object.
0x0000006E The context structure was referenced after being freed.

Parameter 2 depends on the value of Parameter 1.

Parameter 3 depends on the value of Parameter 1.

Parameter 4 depends on the value of Parameter 1.
