If you are experiencing errors related to ntkrnlmp.exe on your Windows 11 system, you are not alone. This file is an essential part of the Windows kernel, which manages core system functions.

Errors involving ntkrnlmp.exe can cause system crashes, freezes, or Blue Screen of Death (BSOD) messages. Fixing these issues requires careful troubleshooting.

In this guide, we will walk you through simple to advanced steps to resolve ntkrnlmp.exe errors on Windows 11 effectively.

By the end, you should have a better understanding of what causes these problems and how to fix them safely.

Quick Note: Before You Begin

  • Backup your important data. Some troubleshooting steps can affect system files or settings.
  • Make sure Windows 11 is updated. Microsoft frequently releases patches that fix known issues.
  • Check for recent changes. New hardware or software installations might trigger these errors.
  • Have your Windows 11 product key and administrator access ready. Certain steps require elevated permissions.

Step 1: Run a Full System Scan for Malware

Malware infections can corrupt system files like ntkrnlmp.exe, causing errors. Running a full system scan helps identify and remove malicious software.

  1. Click the Start button and open Windows Security.
  2. Navigate to Virus & threat protection.
  3. Select Scan options, then choose Full scan.
  4. Click Scan now and wait for the process to complete.

If threats are found, follow the prompts to quarantine or remove them. Restart your PC afterward to see if the error persists.

Step 2: Use System File Checker (SFC) to Repair Corrupted Files

ntkrnlmp.exe is a critical system file. If it becomes corrupted, Windows may display errors. The System File Checker tool scans for and repairs corrupted files.

  1. Press Windows + S, type cmd, right-click Command Prompt, and select Run as administrator.
  2. In the command window, type the following and press Enter: 
    sfc /scannow
  3. Wait patiently as Windows scans and repairs files. This may take several minutes.
  4. Once complete, restart your computer.

This tool replaces damaged or missing system files, which often resolves ntkrnlmp.exe related errors.

Step 3: Run the Deployment Image Servicing and Management (DISM) Tool

If SFC doesn’t fix the issue, DISM can repair the Windows image itself, which helps fix deeper problems.

  1. Open Command Prompt as administrator, as explained in Step 2.
  2. Type the following commands one by one, pressing Enter after each: 
    DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth
  3. These commands check and repair Windows system image corruption.
  4. After completion, restart your PC.

Running DISM followed by SFC ensures both the system files and the image are healthy.

Step 4: Update Your Device Drivers

Outdated or incompatible drivers can cause ntkrnlmp.exe errors because they interact directly with the kernel.

  1. Press Windows + X and select Device Manager.
  2. Expand categories like Display adapters, Network adapters, and Sound, video and game controllers.
  3. Right-click each device and choose Update driver.
  4. Select Search automatically for drivers and follow prompts.
  5. Restart your PC once all drivers are updated.

If Windows doesn’t find updates, visit the hardware manufacturer’s website to download the latest drivers manually.

Step 5: Check for Windows Updates

Microsoft regularly releases updates that fix bugs and improve system stability, which may resolve kernel-related errors.

  1. Press Windows + I to open Settings.
  2. Go to Windows Update.
  3. Click Check for updates.
  4. Download and install all available updates.
  5. Restart your computer after installation is complete.

Keeping Windows up to date ensures you have the latest fixes for system files like ntkrnlmp.exe.

Step 6: Perform a Clean Boot

A clean boot starts Windows with only essential drivers and programs. This helps identify if third-party software causes the error.

  1. Press Windows + R, type msconfig, and press Enter.
  2. In the System Configuration window, go to the Services tab.
  3. Check Hide all Microsoft services.
  4. Click Disable all.
  5. Switch to the Startup tab and click Open Task Manager.
  6. Disable all startup items.
  7. Close Task Manager and click OK in System Configuration.
  8. Restart your PC.

If the error disappears, enable services and startup items one-by-one to find the culprit.

Step 7: Run Memory Diagnostics

Faulty RAM can cause kernel errors like those involving ntkrnlmp.exe. Running a memory test checks for hardware problems.

  1. Press Windows + R, type mdsched.exe, and press Enter.
  2. Select Restart now and check for problems.
  3. Your PC will reboot and perform a memory test automatically.
  4. After the test finishes, Windows will restart again and show the results.

If errors are found, you may need to replace your RAM or consult a technician.

Step 8: Restore Windows to an Earlier Point

If the error started recently, restoring Windows to a previous state can undo problematic changes.

  1. Press Windows + S, type rstrui, and press Enter.
  2. Follow the System Restore wizard to choose a restore point dated before the error appeared.
  3. Confirm and let Windows complete the restoration.
  4. Your PC will restart automatically.

This step is helpful if a recent update or installation caused the issue.
