Windows, the widely used operating system, often encounters various issues. One common issue is the Werfault.exe problem, leading to high CPU consumption. Understanding and resolving this problem is important for the smooth functioning of the Desktop computer. Here’s how you can rectify it.

Understanding Werfault.exe

Werfault.exe, or Windows Error Reporting (WER), is an essential system component that plays a vital role in the functionality and stability of the Windows operating system. Below, we’ll explore its nature, functionality, and significance.

What is Werfault.exe?

Werfault.exe is an executable file associated with the Windows Error Reporting service. This service is an intrinsic part of the Windows operating system, introduced first with Windows XP. Here’s a deep look at what it does:

Error Collection & Reporting

When a software application crashes or encounters an error on a Windows system, Werfault.exe collects information about the problem. This includes details like the application name, application version, module that caused the crash, exception code, and more.

Error Analysis & Feedback

After collecting the necessary information, Werfault.exe sends the error report to Microsoft. Engineers at Microsoft analyze these reports to understand the root causes of the errors. The insights gained can lead to bug fixes, patches, or improvements in future Windows updates.

Importance in Windows

Werfault.exe serves as a bridge between end-users and Microsoft developers. Understanding its importance helps in grasping why it’s an integral part of the system:

1: Enhancing Software Quality

By reporting errors, Werfault.exe contributes to the ongoing development and refinement of both Windows OS and third-party software. It helps developers to identify and fix bugs, enhancing the overall software quality.

2: Facilitating User Assistance

In some cases, Werfault.exe can provide users with immediate solutions or links to knowledge-base articles related to the error. This facilitates self-assistance and guides users on how to resolve common issues.

3: Security Considerations

Werfault.exe operates securely by ensuring that personal or sensitive information is not included in the error reports. It’s designed to focus only on technical data related to the errors, preserving user privacy.

4: Impact on System Resources

Werfault.exe generally operates quietly in the background. However, it can sometimes lead to high CPU or memory usage, especially if there is a sudden surge in application errors or if there is an underlying issue with the system or application itself.

Solutions to Fix Windows Problem Reporting (Werfault.exe) High CPU Issue

Resolving the Werfault.exe high CPU usage problem requires careful analysis and application of suitable methods. It’s essential to admit that there’s no one-size-fits-all solution, and depending on the underlying cause, different approaches might be required.

Quick Fixes

1: Restart the Computer

Restarting the computer is often an overlooked solution that can resolve temporary glitches or conflicts that may be causing Werfault.exe to consume high CPU resources.

  1. Click on the Start Menu.
  1. Choose the power icon.
  1. Choose ‘Restart’. Wait for the computer to reboot and check if the problem persists.

2: Update Windows

Updating Windows can solve known errors and improve stability. To upgrade Windows:

  1. Hit the Start Menu and Go to ‘Settings’.
  1. choose ‘Update & Security’.
  1. Click ‘Check for updates’ and follow the prompts to install any available updates.

Advanced Solutions

1: Disable Windows Error Reporting

If Werfault.exe continues to consume excessive CPU, disabling Windows Error Reporting may be a solution. This step should be considered with caution, as it stops error reporting to Microsoft. To disable:

  1. Press ‘Windows Key + R’ to launch the Run dialog.
  1. Type ‘services.msc’ and hit Enter.
  1. Find ‘Windows Error Reporting Service’ and then do a double-click on it.
  1. Replace the startup type to ‘Disabled’ and click ‘OK’.

2: Scan for Malware

Malicious software can sometimes cause Werfault.exe to behave abnormally. Performing a complete system scan might detect and remove the culprit:

  1. Open Virus & Threat Protection.
  1. Select a full system scan.
  1. Go through the on-screen instructions to remove any detected malware.

3: System File Check (SFC)

Corrupt system files may lead to the Werfault.exe issue. Running a System File Check can repair these files:

  1. Right-click on the Start Menu and choose ‘Windows PowerShell (Admin).’
  1. Type ‘sfc /scannow’ and hit the Enter key.
  1. Wait for the inspection to be fulfilled and follow any prompts to repair files.

4: Rebuild Performance Counters

If performance counters are corrupted, rebuilding them can resolve the problem:

  1. Launch Command Prompt as an administrator.
  1. Type ‘cd \windows\system32’ and hit Enter.
  1. Type ‘lodctr /R’ and press Enter.
  1. Restart the PC and examine if the error is resolved.

These solutions, ranging from quick fixes to more advanced approaches, can effectively address the Werfault.exe high CPU issue. It’s advisable to start with simpler solutions and proceed to more complex ones if necessary. Always take proper precautions, such as backing up essential data, before making significant system modifications.


Werfault.exe, part of Windows Error Reporting, is pivotal in the Windows ecosystem. Its role in collecting, analyzing, and reporting errors contributes to enhanced software quality and system stability. 

While usually operating seamlessly in the background, understanding its function is vital for diagnosing and resolving any issues that may arise, such as high CPU usage. This understanding aids both developers in improving Windows and users in maintaining a smooth computing experience.
