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.

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

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

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fix I found crucial while working on the Kernel Security Check Failure In Windows 11 is promptly updating drivers, as outdated drivers often lead to this error.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Sometimes, the error appears because the system runs on an outdated Windows version.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.
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.
