What is the stop code error “KERNEL SECURITY CHECK FAILURE”?

Kernel Security Verification
Failure is not a virus in and of itself; it is an error message displayed on the screen by Windows 10 when specific data files are corrupted. Malware and virus infections, incompatible settings, memory concerns, erroneous Registry modifications, and other factors can all contribute to data corruption.

Do you dread seeing the Blue Screen of Death, also known as the BSoD?
So, apparently, does the rest of the world! It’s also really aggravating. Unfortunately, the failure of the kernel security check is a “severe” issue that results in a BSOD.

The Kernel Security Check Failure indicates that one or more files failed a compatibility or integrity check and must be updated or replaced.

A “blue screen” error occurs when your system encounters a fatal error. It’s a relatively regular bug that quickly stops your machine and causes it to reboot, dubbed the Blue Screen of Death by Windows users.

It’s an unforeseeable error, but that doesn’t mean there’s nothing you can do to prevent it from happening again for the same reason.

The majority of blue screen errors are caused by regular computer failures and system-related issues. These result in a “STOP” error in Windows, resulting in a system crash. This occurs without warning, which means that work may be lost and files may occasionally become corrupted. Remember to save frequently!

The BSoD appeared somewhat hostile in early versions of Windows, with a screen of text and technical information presented. This has been modified in newer versions to a more understandable error screen, making it easier to determine what mistake you encountered.

If your error code is “KERNEL SECURITY CHECK FAILURE,” you’ve come to the correct spot. This problem commonly happens when upgrading from an earlier version of Windows to Windows 10. It may, however, occur at random while you are using your computer. Whatever the scenario, we’re here to assist you in resolving it.

This is where you can discover the majority of your Windows Update options and configure when you want to get updates.

3. Keep the default Windows Update tab selected.
Select Check for updates and wait for Windows 10 to locate any available updates.

4. If any updates are already visible, click the View all optional updates link to view and install them.

5. If an update is discovered, select Install and wait for Windows 10 to download and install the necessary updates.
Check to see if the Kernel Security Check failure error returns after successfully installing the most recent system version.

Method 2. Update Drivers that Need to be Updated

Device Manager is a simple approach to checking for problematic drivers.

To open Device Manager, hit Windows + X. A tree structure is depicted in the dialogue that will be presented to you.

When you expand all of the nodes in the tree structure, it should be clear which drivers need to be updated – an exclamation mark with a yellow background color will appear next to the nodes that indicate the drivers that need to be updated.

To update a driver, just right-click on the node that represents the driver that needs to be updated and select “Update driver” from the context menu.

You’ll then be presented with two options: either let Windows 10 search for the driver automatically or manually search your computer for the relevant new driver file that may already exist on your machine.

Allow the driver installation update to complete before proceeding.

You can then look for other faulty drivers in Device Manager by looking for nodes with exclamation marks on yellow backgrounds. If you discover any more, you can update those drivers until all of the problematic drivers have been updated.

Then you only need to restart your computer to finalize the modifications brought about by the new drivers.
Hopefully, this resolves your BSOD issue.

If the problem persists, your inquiry must be continued…

Method 3. Check for Viruses

You must confirm that you have updated the most recent Windows updates on your computer and that you are using antivirus software to scan for viruses.

If one or more infections are discovered, take the required steps to eradicate the virus(es) from your computer.

Method 4. Investigate Possible Corrupted Windows File System

To repair faulty system files, utilize the System File Checker (SFC) utility.
The instructions for running the System File Checker utility are outlined below.

  • From the desktop, use the Windows + R key to open the “Run” box
  • In the “Run” box, type in “cmd” then press ctrl+shift+enter to launch the command prompt with administrative privileges.
  • Click the “Yes” button on the “User Account Control”ss (UAC) prompt
  • Type “SFC /scannow” in the command prompt window and press “Enter”.

The System file checker software verifies the integrity of Windows system files and, if necessary, performs appropriate repair procedures.

After the operation is finished, restart your computer.

Method 5. Test to see if Disabling Antivirus Software Fixes the Issue

Antivirus software, no matter how well-intended, might mistakenly prevent non-harmful services and programs from functioning properly.

This method may inform you (in a roundabout way) that your antivirus software may be the source of your problem – but please be aware that running your computer without the protection of adequate antivirus software is not recommended.

Simply launch the task manager to temporarily disable your antivirus software. You can do this by hitting the keys ctrl+shift+escape.

Click the “More details” option if the task manager loads in compact mode. Then, at the top of the “Task Manager” window, click the “Startup” tab.

Locate the name of your antivirus application and choose it from the list.

Then, in the right-hand corner of the Task Manager window, click the disable button.

Finally, restart the computer to see if the BSOD appears again.

Remember that even if this resolves the problem, you should not use your computer without antivirus protection. As a result, you’ll most likely need to look into different security measures.

Method 6. Investigate Possible Issues with RAM

You can use the built-in Windows 10 scanner to identify RAM (memory) issues. Click the search magnifying glass icon in the taskbar or press Windows Key + S to do so.

Enter “Memory Diagnostics” into the search box and select the first option that appears in the search results.

To begin the diagnostic process, select “Restart now and check for problems (recommended)” in the popup dialogue box that appears.

The memory diagnostic process will attempt to uncover probable RAM problems and difficulties during the boot phase.
If any problems are discovered, they will be notified to you.

Method 7. Investigate Possible Hard Disk Drive Issues

Using the check disc utility, you may scan your hard discs for inconsistencies and faults.

To use the check disc program, you must be logged in as an administrator to Windows.
Then take the following steps:

  • Click Windows Key + R on the desktop to open the “Run” box.
  • Enter “cmd” in the “Run” box, then press ctrl+shift+enter to launch the command prompt as administrator.
  • On the “User Account Control” (UAC) prompt, click the “Yes” option.
  • Enter “chkdsk c: /f” onto the command line.

The “/f” option will attempt to correct any problems discovered.

With this command, you might also include the “/r” and “/x” options.
The “/r” option will find damaged sectors and recover any recoverable data, but the “/x” option will force the disc drive (about to be scanned) to unmount before the software starts a scan.

Method 8. Temporarily disable your antivirus

Antivirus software is known to cause problems on computers by interfering with your system and preventing apps and services from working properly. By temporarily stopping your antivirus, you can see if it is causing the Kernel Security Check Failure problem.

It should be noted that this method is not encouraged because using your computer without protection is dangerous. Proceed only if you are aware of the hazards and have a backup of your system to undo any damage that may occur.

1. Right-click on an empty space in your taskbar and choose Task Manager.

2. If the Task Manager is launched in compact mode, make sure to expand details by clicking on the “Mode details” button.

3. Switch to the Start-up tab using the header menu located at the top of the window. Find your antivirus application from the list and select it by clicking on it once.

4. Click the Disable button, which is now displayed in the bottom-right corner of the window.
This prevents the application from running when you turn on your device.

5. Restart your computer to see if the Kernel Security Check Failure problem persists.
To re-enable your antivirus, simply repeat the previous steps and click the Enable button.

Method 9. Start PC in Safe Mode

You can boot your PCs in safe mode so that Windows 10 boots with the bare minimum of files and drivers.
To start Windows 10 in safe mode, follow these steps:

  • To open the Settings App, press the Windows Key + I combination.
  • Select the “Recovery” tab under the “Update & Security” section.
  • In the right pane, click the “Restart Now” button under the “Advanced Startup” title.
  • Select Troubleshoot > Advanced options > Startup Settings > Restart after the PC restarts to the “Choose an option” prompt.

After the computer restarts, you will be provided with a menu of alternatives. To start the computer in Safe Mode, select “4” or press “F4”. If you need to connect to the internet, pick “5” or press “F5” to enter Safe Mode with Networking.

If the problem does not occur in safe mode, it means that the default settings and basic device drivers are not the sources of the problem.

Assuming the problem does not occur in safe mode, you now know that it is caused by a driver or application that runs in regular mode.

You can now focus on the relevant supplementary drivers and applications by using an elimination process.
You can uninstall each of the relevant apps one by one, beginning with the most recently installed and working your way down to the least recently installed.

You can test for the problem with each uninstall. This should help you identify the application or software that was causing the problem. Then, hopefully, uninstall the required program to resolve the issue.
