You went to turn on Windows firewall/Security but you get “these setting are being managed by vendor application…..” error message.

If this is the issue you are having right now, don’t worry. We have got you!

In this guide I will show you how to fix that annoying message “these settings are being managed by vendor application” in Windows 11/10 or 8.

Why do I get “These settings are being managed by vendor application” Message?

As I said at the beginning of this guide, We saw bunch of users on forums complaining that they get this message when they try to turn on Windows firewall or Windows security (known as defender before).

So we did some check in to see why this error coming up.

The main reason for this error is having another antivirus/firewall software installed on the same computer.

Since Windows firewall and Windows security software are preinstalled with Windows, the third party firewall/antivirus software turn them off to avoid software conflicts.

You can see which firewall/antivirus software cause the issue by seeing the message (see the image below).

If turning off antivirus did not work or you want to get rid of third party antivirus, you can uninstall any antivirus software installed on your computer to get rid of “These settings are being managed by vendor application” message and turn Windows firewall/security back on.

It is easy to uninstall antivirus software, just follow these steps below:

  1. Go to settings and then Apps
Windows settings
  1. Scroll down and find the 3rd party antivirus software then click on it
  2. Uninstall button will be visible and then click on it
Uninstalling antivirus
  1. Complete the uninstallation, then restart your computer
  2. Go back and turn on Windows firewall/Security again.

Final thoughts: Do you need 3rd party antivirus/firewall software?

If you are using Windows 10 or 11 computer, both are comes with powerful antivirus/firewall software which is called Windows Security.

If you are not doing heavy internet browsing such as downloading torrents, cracked software, you will be fine with it.

But if you need extra protection and other features such as parent controls, advanced firewall security, then you can purchase a third-party antivirus software and use.

The important thing to know that is usually any third-party antivirus software use significant amount of memory (RAM) and CPU power.

What I recommend is that don’t install any third-party antivirus software if you don’t have at least 6GB of RAM installed on your PC.
