Windows 10: Windows Defender Firewall showing On and Off at the same time

Windows starts with all firewall indications being on. After a few minutes it reports that it is off in the system tray and in Windows Security, but reports on in services.msc and Control Panel. I think it's really on because if I reset the firewall defaults and then try to run a program that accesses the internet, the firewall will ask me for permission. Clicking "Turn On" in Windows Security does nothing. Any idea what's going on here?

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?
