1. Run the System File Checker

The System File Checker (SFC) integrated with Windows 10 can help you identify and resolve a multitude of Windows 10 issues.

  2. Right-click on ‘Command Prompt’ from the search results and choose ‘Run as administrator’. If prompted, enter your password.
  3. Type ‘sfc/scannow’ as a command and hit the ‘Enter’ key on your keyboard.
  4. Wait for the scan to complete. This might take a while. Once it is finished, check to see if any issues were found and if they were corrected.
  5. Restart your computer.

2. Run the Windows Memory Diagnostic Tool

The Windows Memory Diagnostic tool is another scanning tool integrated with Windows 10 that might help identify and resolve your issue. To run the Windows Memory Diagnostic Tool, follow these four steps.

  1. Use the search bar in your taskbar and type in ‘Windows Memory Diagnostic’.
  2. Open the tool from the search results.
  3. Click on ‘Restart now and check for problems (recommended)’. This will immediately restart your computer so make sure to save your files before doing this.
  4. Wait for your computer to restart. During startup, you will see the Windows Memory Diagnostic tool scanning your computer. If an issue is found, the tool will automatically apply a fix.

3. Use an Antivirus Software

If you believe your issue stems from a potential computer virus, then running an antivirus software on your computer will be the most effective solution. The best option for Windows 10 users is Windows Defender. To run Windows Defender on your computer, follow these four steps.

4. Perform a Disk Clean-up

The WerFault.exe issue on your computer could simply be a result of piled up junk stored on your computer’s disk. The program associated with WerFault.exe responds slowly when there is an abundance of temporary junk files stored on your computer’s disk, causing it to time out. You can clear these temporary junk files with the Disk Cleanup utility. To perform a Disk Clean-up, follow these six steps.

  1. Use the search bar in your taskbar and type in ‘Disk Clean-up’.
  2. Open the ‘Disk Clean-up’ utility from the search results.
  3. If prompted, select the drive you want to clear and select ‘OK’.
  4. Wait for the scan to complete. The time this will take depends on the specs of your computer and the number of files you have.
  5. Select the types of files you want to delete under the ‘Files to delete’ section. These are recommended files to select in order to free up space: Windows Update Clean-up, temporary internet files, Windows error reports and feedback diagnostics, delivery optimization files, device driver packages, recycle bin, temporary files, and thumbnails. 
  6. Click ‘OK’ and wait for the Disk Clean-up to finish.

In Conclusion

The WerFault.exe error itself is a typical process for computers that run Windows 10.
