This article explains the sources of this error message and how to fix it.


1. Introduction
2. Antivirus uninstall
3. Windows Restore
4. Error on Windows applications

Introduction :

This error is usually due to a program that can cause problems like an antivirus.
You have probably installed a new application and the error message 0xc0000005 appears.

If the error is not in safe mode, for sure, this is a problematic program.
It only remains to identify the source and uninstall it.

Antivirus uninstall :

Typically, this error is due to security software, antivirus or other.
The free antivirus Avast! could be causing this error past a moment.
Here are some topics on the forum about this error 0xc0000005 and Avast! :

Feel free to test the uninstallation of your protections to see if it corrects errors

Running February 2017, the error 0xC00000e5 has hit users after an update to Avast !, on Windows where Comodo is installed.

The coexistence between an antivirus or firewall can cause problems.
Installing multiple antivirus is also a bad idea.
Clearly, the more protection programs you have, the more likely you will experience crashes or errors because of incompatibility.
Not to mention slowdowns.

We recommend uninstalling Comodo,

Disable Avast! or pass the protections in minimum, see the page: Free Antivirus:

  • Uninstall unnecessary components
  • then open the Control Panel
  • then programs and features.
  • Uninstall Comodo Firewall.

For good protection, you can simply configure the Windows Firewall which may be enough.

In general, to secure Windows, no need to multiply protection programs whose cohabitation can cause problems of Windows instabilities.

Disabling the Avast! Behavior Shield can fix error 0xC00000e5.

  • Go to the Control Panel
  • Programs and Features.
  • Right click on Avast! then Edit.
  • Disable the behavior shield
  • Restart the computer.

Windows Restore :

You can also try a system restore of Windows that allows you to go back to a savepoint.
This will remove the latest program changes and can fix the problems.
Your user data (documents, photos, videos etc) will not be affected.

For it :

  • On your keyboard, press the Windows key + R
  • type rstrui.exe and OK.

Let you guide to find a restore point in the calendar

Error on Windows applications :

Windows Store apps can sometimes crash and display the error 0xC00000e5.

In order to resolve these errors, you can try the following repairs :

  • Try a system file repair including a DISM repair.
  • Open a Windows PowerShell as an administrator by right-clicking on the Start menu and then prompting (admin).

enter the following command:

DISM / Online / Cleanup-image / Restorehealth

Just wait until the process has finished

Final result in cmd :

C:\WINDOWS\system32>DISM /Online /Cleanup-image /Restorehealth

Deployment Image Servicing and Management tool
Version: 10.0.16299.15

Image Version: 10.0.16299.64

[==========================100.0%==========================] The restore operation completed successfully.
The operation completed successfully.

Also try a Powershell repair.
Open Powershell with administrator rights, right-click from the Start / Powershell menu and run as administrator.

Paste the command line:

Get-AppXPackage -AllUsers |Where-Object {$_.InstallLocation -like "*SystemApps*"} | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

And wait until the operation has finished :
