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!
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
- 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.

In some cases, the Kernel Security Check failure error may show up on your device as a result of outdated drivers. In this guide, you can learn how to update drivers and potentially fix issues created by them.
A driver update is only a possible hotfix for the blue screen issue at hand. If this method doesn’t work for you, proceed to the next solution!
- Press the Windows + X keys on your keyboard, and then choose Device Manager from the context menu.
- Expand all of the sections and see if any drivers are outdated. Usually, if a driver is experiencing issues, you’ll see a yellow exclamation mark indicating that something is wrong.
- Right-click on any driver that needs to be updated, and then select the Properties option from the context menu.
- Switch to the Driver tab, and then click on the Update Driver button.
- Select the method of updating your driver. You can either let Windows 10 search for a driver automatically or manually locate a new driver file already on your computer.
- Wait for the driver installation to complete. Update any other drivers that display an error or are outdated.
- We recommend restarting your computer in order to finalize the changes created by the new driver(s). Now, you should test if the BSOD error is still present.
Method 3. Check for disk errors
The Kernel Security Check Security failure issue may be caused by drive errors present on your system. Luckily, these can be fixed with a built-in scanner. All you have to do is follow the instructions below:
- Open a File Explorer window from the taskbar or by using the Ctrl + E keyboard shortcut.
- Click on This PC from the pane on the left. Right-click on your system drive, and then choose Properties from the context menu.
- Switch to the Tools tab, and then click on the Check button. You may be required to have access to an administrator account in order to use this feature.

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.
- Open the Command Prompt in one of the following ways:
- 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.
- Press the Windows + R keys on your keyboard to bring up the Run utility. Type in “cmd” and press the Ctrl + Shift + Enter keys on your keyboard. By doing so, you’re launching the Command Prompt with administrative permissions.
- Press the Windows + X keyboard shortcut, then select Command Prompt (Admin).
- When prompted by the User Account Control (UAC), click Yes to allow the app to launch with administrative permissions.

- First, we’ll run the System File Checker. Type in the following command and press Enter to execute it: sfc /scannow
- 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.
- Next, input the following command and press Enter to execute it: chkdsk C: /f /r /x
- 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:”.
- 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.
Method 6. Use the Blue Screen troubleshooter
BSOD, also known as Blue Screen of Death errors has been present in Windows systems since the very beginning. What used to be a scary and often devastating issue can now be solved by running a simple troubleshooter built into Windows 10.

Method 7. Temporarily disable your antivirus
Antivirus applications are known to cause issues on computers by interfering with your system by blocking apps and services from running properly. You can test if the antivirus you’re using at the moment is causing the Kernel Security Check Failure error by temporarily disabling it.
Note that this method is not recommended as it is unsafe to use your computer without protection. Only proceed if you’re aware of the possible risks and have a backup of your system to revert any damage that may happen.
- Right-click on an empty space in your taskbar and choose Task Manager.
- If the Task Manager launched in compact mode, make sure to expand details by clicking on the “Mode details” button.
- 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.
- Click on the Disable button now visible in the bottom-right of the window. This will disable the application from launching when you start your device.
