You will encounter the Kernel security check failure in Windows 11 when some crucial system files or components do not pass the compatibility or integrity check. A Blue Screen of Death error might cause your system to crash, resulting in the loss of any unsaved data. Issues with memory, incompatible or malfunctioning hardware, problematic Windows updates, or outdated OS are some reasons for this error.

Key Takeaways
  • Kernel security check failure is a BSOD that hinders the Windows startup.
  • Outdated drivers, corrupted system files, malfunctioning hardware, or any virus attack could be the reasons behind this error.
  • Running Windows utilities such as CHKDSK, SFC, or DISM are some of the potential fixes. You can also try updating drivers or Windows or resetting your PC.

Run The SFC Scan

The SFC and DISM Scans diagnose and repair the problematic system and OS-related files. While fixing the error, I found this tool quite helpful. 

The SFC and DISM scans are effective in diagnosing and repairing system and OS-related files that may be causing issues. I found these tools to be helpful in resolving errors, and members of the Hardware forum have successfully employed this method to overcome similar issues.

Here’s how to run the SFC and DISM scans through Command Prompt:

SFC/scannow 
DISM /Online /Cleanup-Image /CheckHealth 
DISM /Online /Cleanup-Image /ScanHealth 
DISM /Online /Cleanup-Image /RestoreHealth

Important: Make sure to enter the commands exactly as mentioned and one after another.

Turn Off Kernel-Mode Hardware-Enforced Stack Protection

While working out a way to resolve the error, I found that turning off the Kernel-mode Hardware-enforced Stack Protection feature from Windows Security fixes the Kernel error well. You can trust this repair method, backed by my first-hand experience and from numerous Windows 11 users. Here’s how to operate:

  1. Go To Device Security: Access Windows Settings > Privacy & Security > Windows Security > Device Security.
  2. Click: Click Core Isolation Detail.

  3. Turn off Protection: You’ll see the Kernel-mode Hardware-enforced Stack Protection option Turn it off via the toggle Yes Restart the PC. 

Fix RAM Issues

Based on my findings while troubleshooting the error, faulty RAM cards can cause the Kernel Security BSOD error. However, running the Windows Memory Diagnostic utility identifies and fixes the malfunctioning RAM. The solution got rid of the error on my PC. Here’s how to run the test:

  1. Windows Memory: Access Windows Search > Type Windows Memory.
  2. Follow Steps: Opt for Windows Memory Diagnostic > Hit Run As Admin > Select Restart Now And Check For Problems.

  3. Check: If faulty memory is mentioned, replace it and check if the error resolves.

Update Drivers And Windows 

Another crucial fix I found crucial while working on the Kernel Security Check Failure In Windows 11 is promptly updating drivers, as outdated drivers often lead to this error. Keep your system’s functionality running smoothly, as it helps eliminate the bugs that might have come with old updates.

Sometimes, the error appears because the system runs on an outdated Windows version. My testing proved that updating Windows and installing the latest version can resolve the Kernel error.

Reset The Windows

If none of the fix methods are working out, then as a last approach, you can try resetting the Windows to fix the error. This step resolves the BSOD errors for Windows 11 in most cases but requires data backup beforehand, as you may lose the settings and apps. I went with a soft reset by choosing to Keep My Files, and it was successful.


Tip: Secure your files by selecting Keep My Files while other app settings will be removed. All files and system settings will be reset by opting for the Remove Everything option.

Users across Eleven Forum reported that their PCs suddenly turned off, and upon restarting, they encountered the error. The same was true for me since my PC was restarting in a loop, and I could not boot to the Windows interface. After testing the methods above, the Windows returned to its regular operation, leaving the BSOD.
