Hi AnudieKatz.

Thank you for writing to Microsoft Community Forums.

Since you are facing an issue with the Windows Defender firewall, I would like to ask you few questions to get a better picture.

1. Are you using any other Anti-virus software?
   
2. Since when are you facing this issue?
   
3. Have you tried installing Picture viewer and Calendar app after it getting uninstalled?
   

Based on your information, I would like to inform you that if you are using third party anti-virus program Windows defender will automatically turn off from your system you will not able turn it on manually.

Let’s try simple troubleshooting steps and check if this helps in resolving the issue. Follow the below methods.

Method 1: Check the following services and ensure it is started.

1. Press Windows and R key together on your Keyboard.
   
2. Type Services.msc and hit Enter.
   
3. Search for the following services:
   

• Base filtering engine Service
• Remote Procedure Call Service
• Windows defender firewall service

4. Start the above services and reboot the device.

Method 2: I would suggest you to try running the troubleshooter to enable the firewall. Use the below link to run the troubleshooter.

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 + Windows FTP Server

Why is windows defender firewall disobeying my firewall rules?

• Enabled Windows FTP Servers via Windows 10 Features.
• Rules are in the firewall allowing FTP access for both passive & control (rules were injected through enabling the service).
• FTP packets are dropped by the firewall still (confirmed in the logs) but no rule is given, just "DROP".
• This is over a VPN that is being detected as "Unidentified Network" thus putting the interfaces in the "Public" zone.
• FTP rules apply to all three zones (Public, Private, and Domain).
• Turning off Windows Defender Firewall for the specific zone allows the FTP transaction.
• There are no rules denying this traffic in the list.
