How to fix werfault.exe and optimize the process?


The Werfault system is running in the background. This gives her the right to run at any opportunity. CPU overload occurs due to eating up computer memory. One process of Werfault.exe is not terrible, but when there are about three or four of them running, then there is a slowdown in the OS and a failure “Werfault.exe – Application Error” appears.

How to determine the essence of the fault

  1. On the keyboard, press the combination WIN (flag icon) + R.
  2. Run will open before us. We bring here msconfig.
  3. System configurations will appear. We remove the check mark from “Normal start” to “Diagnostic start.” OK and restart the computer.

Run the Windows diagnostic mode

This method will help you understand exactly whether the problem is a system problem or is created by a third-party program. All autoruns will be disabled, and “clean” Windows will start, if failure notification will not appear, then the problem is in a third-party application and vice versa.

The first thing to do to troubleshoot the Werfault.exe application error on the computer is to make a diagnostic system start, which only loads the basic drivers and starts the basic services. The diagnostic start is something similar to running the system in safe mode.

  1. Run the Msconfig command in the Win + R window.
  2. In the general tab, select the Diagnostic start item and click OK to apply the changes.

If you ask what it will give us, then everything is simple. The next time the system is restarted, if the error of the Werfault.exe application disappears, this means that the problem lies in the installed programs. If not, then it will be a little more difficult. Do not forget to disable diagnostic system startup in the future. So, we analyze two cases:

The first case: The error does not appear after the diagnostic system startup

The first thing we check your operating system for viruses or malware in any way. If you use the latest version of the Windows 10 operating system, then you can even use a Windows defender anti-virus tool.

Then you need to clean the computer from the tails of remote programs. To do this, you can use specialized programs, such as CCleaner. You can read more about this in the article on how to clean the C drive from unnecessary files.

Next, to solve the problem, you need to remove unnecessary programs. It is worth starting with the ones you installed last. To do this, you can also use CCleaner or the built-in tool for removing Windows 10 programs.

The second case: The error also appears during diagnostic system startup

Here you need to check to verify the integrity of Windows 10 system files. For more detail on how this can be done, read our article.

  1. Run the command prompt as administrator.
  2. Run the sfc / scannow command and wait for the process to complete.

After the process is completed, you will receive data on the results of the verification. If problems are found, then the system will automatically repair them.

The second way for this case is to roll back the system to the previous version or to reset the operating system settings completely since not everyone will be able to restore the previous version. This method is relevant in cases where after the update, for example, to Windows 10, this error appeared.

How to disable the service Werfault.exe

If nothing has helped and you do not want to do a reset, then you can try to disable the application service completely. In the Windows 10 operating system, due to repeated updates, the service appears as a Windows information collector whose name is WerSvc.exe.

If we talk about previous versions, such as Windows 7, then you can come across the name Windows Error Reporting Service.

  1. Run the services.msc command in the Win + R window.
  2. In the list of services, we are looking for the WerSvc.exe or Werfault.exe service  (whose display name is Windows Information Collector or Windows Error Reporting Service).
  3. Open the service and change its startup type to Disabled.

Disabling the service on the Windows 10 operating system helps very rarely, this method is more suitable for users of the Windows 7 operating system. Therefore, if the application error has not disappeared, then you still have to use the method suggested above.


Werfault.exe application error is very common for both Windows 10 users and previous operating systems. Therefore, we have collected ways to solve the problem so that you can fix the error yourself.

Rollback updates


If the error began to appear from a certain point, you should remove the latest Windows updates. An example of this video will help you find them and roll back. Find in the list the latest updates of Windows (navigate by date) and remove them.

These are all effective ways to help solve the “Application Error – Werfault.exe” and the problem of high loads. As a last resort, reinstall Windows.
