  1. Windows 10 Defender firewall will not turn on


    I use Windows 10 on my laptop. I cannot turn on my firewall nor can I download any software, not even from Microsoft Store. If I can not download software then I can't reinstall my Windows 10. Any suggestions?

    :)

    Hi Faye,

    Third-party antivirus programs usually have their own uninstallers provided by the software developer. We suggest checking the developer's website or contacting their support team for assistance with uninstalling their program. After fully uninstalling the
    third-party antivirus software, you may turn on Windows Defender by following these steps:

    • Click Start.
    • Type Windows Defender Security Center and press Enter.
    • Click Firewall and network protection.
    • Click Private (discoverable) network and click On.
    • Click Public (non-discoverable) network and click On.

    Let us know if you have any other concerns about Windows Defender.

    Windows Defender Firewall

    I am using Windows 10 on a Dell desktop. This set-up came with a McAfee firewall installed (trial offer, I guess). I uninstalled McAfee (using McAfee's removal tool) so I could use Windows Defender firewall. Now it appears I have neither. The below screenshot
    shows the McAfee firewall is still installed and the Windows Defender firewall cannot be turned on because I'm using another firewall provider. The setup>programs and apps>uninstall routine does not list McAfee as a program to be uninstalled. Services does
    not list McAfee as a service to be turned off. How can I get this logjam fixed?

    Finally, Weybrew!

    Turn Windows Defender Firewall on or off

    You should always run Windows Defender Firewall even if you have another firewall turned on. Turning off Windows Defender Firewall might make your device (and your network, if you have one) more vulnerable to unauthorized access.


    • To turn Windows Defender Firewall on or off, select the Start button, and then select Settings > Update & Security > Windows Security > Firewall & network protection. Choose a network profile, and then under Windows Defender Firewall, switch the setting to On or Off.
    • Note: If your device is connected to a network, network policy settings might prevent you from completing these steps. For more info, contact your administrator.

    This comes directly from Microsoft and the first sentence says it all! Don't turn off Windows Defender or its firewall!

    Yup, I was wrong and I'm sorry I misled you. Here's the URL:
