    Windows Defender firewall prevents home network access


    On my home network between 2 Win 10 pcs the windows firewall will not allow pc2 to access pc1 unless I manually turn off the firewall. It is OK going the other direction.
    Pc1 automatically turns on the firewall every day causing me to again have to manually turn it off. I have even put the network address in the box to be allowed through. Doesn't work.

    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.

    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:
