How to Fix a System File Error

Blue screen concerns, unexpected restarts, and application-launch failures may be the result of “FWPKCLNT sys” errors. While others can be repaired automatically by your operating system after it has crashed, some cases of these errors require your input. Although many programmers argue that it is not a threat, fixing the system error immediately is suggested. Otherwise, with its occasional intervention, attending to even the simplest tasks such as editing an image or printing out a document may not be accomplished.


FWPKCLNT is a system file linked to Windows 8 Pro developed for Windows OS. Like all other similar files, which you can also refer to as kernel mode device drivers or IPsec API file, it is a critical third party device driver packaged as a component of the operating system. Having it installed in the system means internal or attached PC hardware, firmware, software, and device driver (e.g. mouse, printer, speaker, etc.) are enabled to function with third party software (e.g. media player, word processors, web browsers, etc.).

What Is FWPKCLNT.sys Error?

An error with FWPKCLNT or blue screen of death error is a malfunction that occurs if the device driver, firmware, or hardware meant for assisting with the execution of the file has failed to work accordingly. Either that or it has been prevented (often by virus or malware) to load during program or computer startup. Since it is an important file, a fault with it is likely to result in critical system errors.

The Cause of “FWPKCLNT.sys” Error

“Kernel” file or any associated file is damaged
Kernel Mode Trap loading process has been stopped
Kernel Trap file is missing or corrupt
A Kernel Mode Trap file has a corrupted memory
FWPKCLNT or any related Windows 8 Pro file is infected by malware or virus
Hardware, firmware, software, or device driver is damaged
Hardware, firmware, software, or device driver is in conflict with recently installed component
Recently installed FWPKCLNT is corrupted
Windows 8 Pro drivers are old, corrupted, or incorrectly configured

With FWPKCLNT bsod, Win 7, Windows 8, Windows ME, Windows XP, or any Windows versions can result to a system crash. Although it has not been found to carry malware, Trojan, spyware, or virus, it disrupts normal processes. It is recommended that prior to any new installation, be this hardware or device driver, the condition of a component is checked for functionality. Otherwise, it should be repaired or replaced.

Examples of FWPKCLNT.sys Error Messages

FWPKCLNT bad pool header
Kernel Mode Trap Windows 7 or Windows 8 path not found
System has stopped working due to kernel errors
Unexpected Kernel Mode Trap bsod (blue screen of death)
System files are incomplete
Kernel Mode Trap location is unknown
Kernel file is missing or corrupt

FWPKCLNT errors or bsod errors appear commonly during the use of any program requiring third-party hardware, device driver, firmware, or software or after installation of a new component. However, since the kernel loads every time Windows or a program loads, they can also come up during program startup and computer startup or shutdown. Once your system detects that there is a flaw in the regular processes, it can result to a sudden crash.

Can FWPKCLNT.sys Be Downloaded?

Since it can be downloaded from system files distributors, others who are troubled with system file errors can replace the file instead of getting it fixed. In most cases, if the Kernel Trap file is missing, damaged, or corrupted, some vital Windows files are known to have a similar problem. Although relying on another source and repairing the specific file alone seem an effortless alternative, it is not recommended. Rather, start anew by reinstalling your operating system.
