Windows 10: Windows 10 Firewall All Ports Open !

    Windows 10 Firewall All Ports Open !


    I was frankly shocked to find My Windows 10's Firewall having SEVERAL rules applying within the Public profile and allowing all traffic to hit local ports. I am using Public profile.

    One Rule was called "Connect" and was allowing ALL.

    When All ports are allowed inbound, basically you do not have a firewall. Since every port can be reached.

    Here is a screenshot of one of the rules I had in my firewall.

    I don't know how those rules got added. I don't have much games on my PC. Just one ( though tried few on Steam ) . No illegal software ( well maybe one piece) and yet my firewall is literally out.

    Why Why Why. If someone like me could miss something like that, than every average PC user will.

    Seems to me like Microsoft is as insecure as it was before the introduction of the firewall in Windows XP.

    How can I check the effective opened ports. So many rules ffs.

    What makes you think that cortanna would respond to requests on all ports. That particular rule allows cortanna to use the web for searches.

    Hi there, ten111. Welcome to Windows TenForums.

    As you know, apps and games may change firewall rules. You may want to:

    Right click on the Security Center shield icon in the systray > Click "Open" > Click "Firewall and network protection" > Click "Restore firewalls to default".

    You may want to try GRC

    Snug as a bug in a rug here.
