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. It is a Blue Screen of Death error that 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 Issues with memory, incompatible or malfunctioning hardware, problematic Windows updates, or outdated OS are some reasons for this error.

Here’s how the error message appears:
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- Outdated drivers, corrupted system files, malfunctioning hardware, or any virus attack could be the reasons behind this error.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.
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
Run A Disk Check
While trying to find the possible causes behind the Kernel error, I realized that disk issues could also be the cause. So, I performed a disk check to check the hard drive for any corruption, thereby fixing errors/bugs and freeing some disk space.
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. Moreover, this also seems to work for many users facing this problem.
Here’s how to operate:
- Access Windows Settings > Privacy & Security > Windows Security > Device Security.
- Click Core Isolation Detail.

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

Sometimes, the error appears because the system runs on an outdated Windows version. My testing proved that the Kernel error can be resolved by updating Windows and installing the latest version.
Update Drivers
Another important fix I found crucial while working on the Kernel Security Check Failure In Windows 11 is to promptly update 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.
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.
Users across Reddit reported that their PCs suddenly turned off, and upon restarting, they encountered the error. The same was the case 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 normal operation, getting out of the BSOD.
