    Windows 10 Defender Firewall can't be turned off


    Windows 10 Pro r1903
    Recently recovered from failing hard disk.
    After data recovery (onto new hard drive), this computer could not been seen by others in the same network. I could not even ping it.
    Network discovery on.... the usual was checked. Then research says check the firewall settings.
    I was getting errors when opening firewall app. Just says settings are not as recommended. I get an error 0x8007045B when I click "Use recommended settings".
    Click Advanced settings and get: An error occurred while trying to open the policy. Error: A system shutdown is in progress. Code: 0x45B
    Ran: DISM /online /cleanup-image /restorehealth /source:C:\zzwin10\sources\install.wim (a known working wim)
    DISM Completed successfully
    Ran sfc /scannow and it reported it successfully repaired all. Log confirmed.
    Rebooted but error still persists.
    Ran: netsh advfirewall show allprofiles and got this:
    An unrecoverable Windows Defender Firewall error (0x45b) occurred.
    This is what is displayed when I open the firewall service. Services shows it running, but properties dialog gives no option to stop, etc. All grayed out. Base Filtering Engine properties shows the same, running and no way to stop and restart.

    I believe something in the firewall is keeping this computer from being seen by others on the same network. I cannot even ping it. Troubleshooter on another computer reports:
    Windows can't communicate with the device or resource (192.168.1.225) Detected Detected

    It is available but is not responding to connection attempts. A firewall or network security policy on the remote computer might be blocking the connection on port "file and print sharing resource".
    However, it can see and copy files to other computers.
    What can I do now to fix this?

    :)

    windows defender firewall

    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?

    Firewall Windows 10... reset?


    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:
