What are KmxFw.sys Error Messages?


KmxFw.sys Blue Screen of Death (BSOD) Errors

There are a number of reasons why you could be encountering issues with KmxFw.sys. Most of the issues concerning sys files involve Blue Screen of Death (BSOD) errors. These types of KmxFw.sys errors can be cause by hardware problems, outdated firmware, corrupt drivers, or other software-related (eg. Tiny Personal Firewall update) issues. Some of these errors include:

A problem has been detected and Windows has been shut down to prevent damage to your computer. The problem seems to be caused by the following file: KmxFw.sys.

:( Your PC ran into a problem that it couldn't handle, and now needs to restart. You can search for the error online: [BSOD] (KmxFw.sys).

<strong>STOP 0x0000001E: KMODE EXCEPTION NOT HANDLED (KmxFw.sys)</strong><br /><strong>STOP 0x00000050: PAGE FAULT IN A NONPAGED AREA (KmxFw.sys)</strong><br /><strong>STOP 0x0000000A: IRQL NOT LESS EQUAL (KmxFw.sys)</strong><br /><strong>STOP 0x0000007E: SYSTEM THREAD EXCEPTION NOT HANDLED (KmxFw.sys)</strong><br /><strong>STOP 0×0000007A: KERNEL DATA INPAGE (KmxFw.sys)</strong><br /><strong>STOP 0x0000003B: SYSTEM SERVICE EXCEPTION (KmxFw.sys)</strong>

It's Critical to Resolve Blue Screen of Death Errors

In the majority of cases, you will encounter KmxFw.sys BSOD errors after you've installed new hardware, software (Tiny Personal Firewall), or performed a failed Windows Update. In other cases, software corruption caused by a malware infection can lead to KmxFw.sys Blue Screen of Death errors. Therefore, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.


GEEK TIP : As a rule of thumb, it's always a good idea to create a Windows "Snapshot" backup / System Restore Point before making any hardware or software changes to your computer. That way, it's very easy to restore your system in the unfortunate event you encounter a KmxFw.sys Blue Screen of Death error after recent changes.

How to Fix KmxFw.sys Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your KmxFw.sys issue. These troubleshooting steps are listed in the recommended order of execution.


Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. When you see the search box, type "System Restore" and press "ENTER".
  3. In the search results, find and click System Restore.
  4. Please enter the administrator password (if applicable / prompted).
  5. Follow the steps in the System Restore Wizard to choose a relevant restore point.
  6. Restore your computer to that backup image.

If the Step 1 fails to resolve the KmxFw.sys error, please proceed to the Step 2 below.

Step 2: If recently installed Tiny Personal Firewall (or related software), uninstall then try reinstalling Tiny Personal Firewall software.

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many KmxFw.sys error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

  3. In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
  4. If updates are available for download, click "Install Updates".

Download KmxFw.sys Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying KmxFw.sys to your appropriate Windows system directory. Tiny Software typically does not release Tiny Personal Firewall SYS files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing KmxFw.sys and all other SYS files for Tiny Personal Firewall. An incorrectly installed SYS file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
