The KMODE_EXCEPTION_NOT_HANDLED error, identified by the code 0x0000001E, occurs when a kernel-mode program triggers an exception that isn’t intercepted by the error handler.

This issue commonly manifests as a blue screen error during the installation of a program or the loading of Windows drivers at system startup or shutdown. Additionally, this error can arise from improperly configured device drivers.

1. Disable Fast Startup

Fast Startup is a feature in Windows 10 designed to reduce the time your system takes to boot up. However, it can occasionally lead to compatibility issues with hardware devices, resulting in the KMODE_EXCEPTION_NOT_HANDLED error.

  • Function: Fast Startup combines elements of a cold shutdown and the hibernate feature. This means when you shut down your device, it’s not a complete shutdown, potentially leading to errors.
  • Issue: By preventing a complete shutdown, Fast Startup may cause conflicts with hardware devices or drivers, leading to the error.
  • Solution: Disabling the Fast Startup feature can often resolve these compatibility issues.
  • Steps to Disable:
    1. Go to the Control Panel and navigate to Power Options.
    2. Select ‘Choose what the power buttons do’.
    3. Click on ‘Change settings that are currently unavailable’.
    4. Uncheck the box next to ‘Turn on fast startup (recommended)’.
    5. Save changes and restart your computer.

2. Update Faulty Drivers

Outdated or corrupted drivers are significant causes of the KMODE_EXCEPTION_NOT_HANDLED error. Updating these drivers can resolve the issue.

  • Automatic vs Manual Update: Drivers can be updated automatically using software applications or manually through the device manager.
  • Manual Update Process:
    1. Press ‘Windows’ and ‘X’ keys simultaneously and select Device Manager.
    2. Expand the ‘Other Devices’ section.
    3. Right-click on the device with the outdated driver and select ‘Update Driver’.
    4. Choose ‘Search automatically for updated driver software’ and follow the on-screen instructions.
  • Compatibility: Ensure the updated driver is compatible with your Windows operating system.

3. Uninstall Faulty Software/Driver

Recent changes, such as installing new software or hardware, can lead to the KMODE_EXCEPTION_NOT_HANDLED error if they are incompatible with your system.

  • Identifying the Culprit: Check for any recent hardware or software additions that might have caused the error.
  • Uninstallation Process:
    1. Press ‘Windows’ and ‘R’ keys to open the ‘Run’ dialog box.
    2. Type ‘Control Panel’ and press Enter.
    3. In the Control Panel, set the view to ‘Category’ and click on ‘Uninstall a program’ under ‘Programs’.
    4. Examine the list of recently installed applications and uninstall any that may have caused the error.
  • Reverting Changes: Removing or uninstalling the recent changes can often reverse the error and restore normal functioning.

4. Enter Safe Mode and Install Missing Drivers

If driver files are corrupted or missing, the KMODE_EXCEPTION_NOT_HANDLED error can occur. Installing missing drivers in Safe Mode is an effective solution.

  • Accessing Safe Mode: Safe Mode loads Windows with a minimal set of drivers and can help troubleshoot issues.
    1. Restart your computer.
    2. Press F8 at 1-second intervals during the boot-up process.
    3. Select ‘Safe Mode with Networking’ from the options.
  • Installation Process in Safe Mode:
    1. Once in Safe Mode, press ‘Windows’ and ‘X’ keys to open Device Manager.
    2. Locate ‘Other Devices’ and right-click to update the driver.
    3. Select ‘Search automatically for updated driver software’.
    4. If automatic search fails, choose ‘Browse my computer for driver software’.
  • Restart: After installing missing drivers, exit Safe Mode and restart your computer to check if the issue is resolved.

5. Repair Problem Using Windows

The System File Checker (SFC) scan in Windows can solve many issues, including the KMODE_EXCEPTION_NOT_HANDLED error, by checking for and repairing corrupt files.

  • Running SFC Scan:
    1. Press ‘Windows’ and ‘R’ keys to open the ‘Run’ dialog box.
    2. Type ‘cmd’ to open the Command Prompt.
    3. Enter the command ‘sfc /scannow’ and press Enter.
  • Process: The SFC scan will check all system files and replace corrupted files with a cached copy.
  • Completion: The scan may take some time to complete. Once finished, restart your Windows 10 computer to see if the error has been resolved.

6. Run Windows Memory Diagnostics

Windows Memory Diagnostics can detect and solve issues related to system memory, which can be a cause of the KMODE_EXCEPTION_NOT_HANDLED error.

  • Diagnostic Process:
    1. Open the Control Panel and go to ‘System and Security’.
    2. Select ‘Administrative Tools’ and then ‘Windows Memory Diagnostics’.
    3. Choose ‘Restart now and check for problems’.
  • Function: This tool tests the computer’s RAM for issues and highlights any problems in the status bar.
  • Resolution: The tool will attempt to fix any detected issues with your computer’s memory, potentially resolving the error.
