    Kernel Security Check Failure

Blue screen errors, also known as BSOD errors, often cause issues for Windows 10 users. They may cause data loss, delete your progress, and in some cases may cause damage to your device. Luckily, each blue screen error comes with a stop code to help identify why the crash happened and how to fix it.

If you just experienced a blue screen error with the “KERNEL_SECURITY_CHECK_FAILURE” stop code, don’t worry. In this article, we’ll go over each working method to troubleshoot this issue in Windows 10.

What is “KERNEL_SECURITY_CHECK_FAILURE” stop code error?

Kernel Security Check Failure is not a virus in itself, it is an error message that Windows 10 displays on the screen when certain data files are corrupted. The root cause of data corruption may indeed be malware and virus infections, incompatible settings, memory issues, incorrect Registry changes, and more.

Do you dread seeing the Blue Screen of Death or BSoD? Well, so does the rest of the world! And it’s extremely annoying as well. Unfortunately, the kernel security check failure is a “serious” error resulting in a BSOD.

The meaning of the Kernel Security Check Failure is that one or several files failed a compatibility or integrity check and you have to update or replace it.

When your system suffers a fatal error, you get a “blue screen” error. Nicknamed the Blue Screen of Death by Windows users, it’s a relatively common issue that immediately stops your system, and forces it to reboot.

It’s without a doubt an unpredictable error, but that doesn’t mean there’s nothing you can do to ensure it doesn’t happen twice for the same reason.

Most blue screen errors are associated with common computer errors and system-related issues. These cause Windows to receive a “STOP” error, leading to a system crash. This happens without a warning, meaning that work can be lost, and files can occasionally get corrupted. Make sure to save frequently!

The old version of Blue Screen of Death, from NeoSmart Knowledgebase


In older versions of Windows, the BSoD appeared rather unfriendly, with a screen of text and technical information displayed on the screen. This has been changed in recent versions to a more comprehensible error screen, making it simpler to identify what error you ran into.

If your error code reads “KERNEL_SECURITY_CHECK_FAILURE” you’re in the right place. This error usually appears after upgrading to Windows 10 from an earlier version. However, it may happen randomly while you’re using your computer. No matter the scenario, we’re here to help you solve it.

Common causes for “Kernel Security Check Failure” error

Unlike most errors in Windows 10, the causes of blue screen errors are more often than not easy to identify. The kernel security check failure happens due to:

  • Memory problems
  • Outdated drivers
  • Viruses
  • Corrupted Windows system files
  • Security programs
  • A damaged or corrupted hard disk

So, if you’re currently dealing with the Kernel Security Check Failure stop code, the possible causes are:

  • Your system is outdated — It’s possible that your system suffered a Kernel Security Check failure because it’s outdated. In this case, all you have to do is acquire the latest available Windows 10 update. Updates help keep you safe and often fix present bugs, errors, and more.
  • You have malware on your system — Users have reported that after scanning for malware and removing the identified threats, the Kernel Security Check failure was resolved. It’s possible that your system is infected by malware which is causing the error.
  • A driver is outdated or not compatible — Similarly to your system, your drivers need updates to be kept up-to-date to function as intended. If a driver is old, it may run into compatibility issues with the rest of your drivers.
  • Corrupt system files — Most likely as a result of malware, your system files could be damaged. These files can easily be restored with the help of the SFC scan and disk check commands.
  • Third-party security or antivirus — If you’re currently using a third-party antivirus, it may cause interference in your system. We recommend following the steps below to temporarily disable it and see if your situation improves.

Out of these, the most common is incompatible drivers, especially if you’ve upgraded to Windows 8 or 10 from an older version. In all likelihood, you might be using a driver that worked well for previous versions but not for the current one. In such a case, the system throws this error.

Typically, there’s a check process in Windows operating system during startup. This process throws the KERNEL_SECURITY_CHECK_FAILURE error when it detects corruption in any critical data structure.

Warning: Some methods below may only work if you can get access to your computer without crashing. If your device is completely unable to boot, we recommend getting in touch with Microsoft’s customer service team.

Method 5. Run the System File Checker and ‘chkdsk’ commands

The System File Checker is a tool available in most versions of Windows by default. It’s also called an “SFC scan,” and it’s your quickest way to automatically fix corrupted system files and a plethora of other issues.

If the SFC scan didn’t work, continue with the steps and try running ‘chkdsk’ to repair your PC. The Check Disk command attempts to identify and eliminate disk issues, which may help you resolve issues with the Kernel Security Check failure.

  1. Open the Command Prompt in one of the following ways:
    1. Open the Search function in your taskbar, or alternatively use the Ctrl + S keyboard shortcut to bring up the search bar and look up “Command Prompt”. When you see it in the results, right-click on it and choose Run as Administrator.

  2. When prompted by the User Account Control (UAC), click Yes to allow the app to launch with administrative permissions.
  3. First, we’ll run the System File Checker. Type in the following command and press Enter to execute it: sfc /scannow
    sfc scannow
  4. Wait for the SFC scan to finish scanning your computer and repairing corrupt files. This may take a long time; ensure that you don’t close the Command Prompt or shut your computer down.
  5. Next, input the following command and press Enter to execute it: chkdsk C: /f /r /x
    check disk
  6. This command is going to check the C: drive. If your Windows 10 has been installed on a different drive, make sure to modify the command accordingly by replacing “C:”.
  7. Wait for the Check Disk command to finish running. It’ll attempt to fix issues with the drive and recover any readable information. Restart your device once both commands have been executed.
