How to Fix Kernel Security Check Failure Error in Windows 10

Update Drivers

Ensure all device drivers are up to date by visiting the manufacturer’s website or using Windows Update. Updating drivers can fix compatibility problems and improve system strength.

Run System File Checker

Use the System File Checker (SFC) tool to examine and restore corrupted system files. Open Command Prompt as an administrator and type “sfc /scannow” followed by Enter. Allow the scan to complete and follow any repair instructions.

Check for Memory Issues

Run Windows Memory Diagnostic to check for memory-related problems. Press the Windows key + R, type “mdsched.exe,” and press Enter to launch the tool. Follow the on-screen instructions to start the memory test.

Perform a Clean Boot

Start Windows in a clean boot state to troubleshoot software conflicts. Press Windows key + R, type “msconfig,” and press Enter. In the System Configuration window, navigate to the Services tab and check “Hide all Microsoft services.” Click “Disable all” and restart the computer.

Scan for Malware

Conduct a complete scan for malware using trustworthy antivirus software. Malicious software can corrupt system files and interfere with the kernel’s operation, leading to security check failures.

Check Hardware Components

Inspect hardware components for signs of damage or malfunction. Ensure all connections are protected and free from dust or debris. Consider running diagnostic tools provided by the hardware manufacturer to identify any issues.

Preventive Measures to Avoid Kernel Security Check Failure

Regular System Maintenance

Schedule regular maintenance tasks such as disk cleanup, defragmentation, and software updates to keep the system optimized and free from errors.

Update Operating System and Drivers

Stay up to date with the latest Windows updates and device drivers to benefit from security patches, bug fixes, and performance enhancements.

Use Reliable Antivirus Software

Install reputable antivirus software and keep it updated to safeguard against malware infections that can compromise system integrity and stability.
