How to Fix Custom Error Module Not Recognized Error on Windows 11: Step-by-Step Solutions

Encountering the “Custom Error Module Not Recognized” error on Windows 11 can be confusing and frustrating. This issue usually appears when the system fails to identify or load a required error module, causing interruptions in your workflow.

Fortunately, there are several straightforward steps you can follow to resolve this problem. These solutions range from simple system checks to more advanced troubleshooting methods.

This guide will help you understand and fix the issue step-by-step, even if you are not very tech-savvy.

Let’s begin with some quick notes before diving into detailed solutions.

Quick Note: Prerequisites and Initial Checks

  • Restart your computer: Sometimes, a simple reboot can clear temporary glitches causing the error.
  • Check Windows Updates: Make sure your system is up to date, as many errors are fixed through updates.
  • Backup important data: Before making any changes, it is always safe to back up your essential files.
  • Administrator access: Ensure you are logged in with an administrator account to perform system changes.

Step 1: Run Windows System File Checker (SFC)

The System File Checker is a built-in Windows tool that scans and repairs corrupted system files. Sometimes, the “Custom Error Module Not Recognized” error can happen due to damaged or missing files.

  1. Press Windows + S and type Command Prompt.
  2. Right-click on Command Prompt and select Run as administrator.
  3. In the command window, type sfc /scannow and press Enter.
  4. Wait patiently as the scan may take some time. It will automatically fix any detected issues.
  5. Once complete, restart your computer and check if the error persists.

This step is important because corrupted system files are a common cause of many Windows errors, including this one.

Step 2: Use Deployment Image Servicing and Management (DISM) Tool

If the SFC scan does not fix the problem, the DISM tool can repair the Windows system image, which might be causing module recognition issues.

  1. Open Command Prompt as an administrator (same as in Step 1).
  2. Type the following commands one by one and press Enter after each:
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth

These commands check for corruption and restore system health automatically. After completion, reboot your PC.

Step 3: Check and Update Device Drivers

Outdated or faulty device drivers can cause various errors, including module recognition problems. Keeping drivers updated ensures smooth communication between hardware and software.

  1. Press Windows + X and select Device Manager.
  2. Look for any devices with a yellow exclamation mark—this indicates a driver issue.
  3. Right-click on such devices and choose Update driver.
  4. Select Search automatically for updated driver software and follow the instructions.
  5. Repeat for all devices with issues, then restart your computer.

Alternative: Use Manufacturer’s Website

If Windows cannot find new drivers, visit the hardware manufacturer’s website to download and install the latest drivers manually.

Step 4: Perform a Clean Boot

Sometimes, third-party applications or services conflict with Windows processes, causing errors. A clean boot helps isolate these conflicts by starting Windows with only essential services.

  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 at the bottom.
  4. Click Disable all to turn off non-Microsoft services.
  5. Go to the Startup tab and click Open Task Manager.
  6. In Task Manager, disable all startup items by selecting each and clicking Disable.
  7. Close Task Manager and click OK in the System Configuration window.
  8. Restart your computer.

If the error disappears, a disabled service or startup item was causing the problem. You can re-enable services and startup programs one by one to find the culprit.

Step 5: Check for Malware or Virus

Malware infections can corrupt system files or interfere with system modules. Running a full antivirus scan is essential to rule out this cause.

  • Open Windows Security by searching it in the Start menu.
  • Go to Virus & threat protection.
  • Click Scan options and select Full scan.
  • Start the scan and allow it to complete.
  • If threats are found, follow the recommended steps to remove them.

Step 6: Reset Windows 11 (Advanced Option)

If none of the previous steps work, resetting Windows 11 can fix deep system issues by reinstalling Windows without deleting your files.

  1. Open Settings via Windows + I.
  2. Go to System > Recovery.
  3. Click Reset PC next to Reset this PC.
  4. Choose Keep my files to preserve personal data.
  5. Follow the on-screen instructions to complete the reset.

Note: This is a last-resort step as it reinstalls Windows and removes installed applications.
