Can't block outbound traffic on port 80 using Windows 10 firewall

fj flag

I'm trying to block port 80 using Windows 10's firewall however it seems like no matter what I try I can still access HTTP sites.

I've been testing weather the port using the following powershell command: Test-NetConnection -ComputerName portquiz.net -Port 80 which could be the issue however I have tried with other sites.

I firstly tried using the Windows defender GUI with the following settings

I then tried replicating the same rule using Powershell as an administrator with this command, but to no avail.

I also tried disabling all other firewall rules in case another is interfering and that didn't work either so I really don't know what I could be doing wrong

you could have followed the documentation:

PS C:\> New-NetFirewallRule -DisplayName "Block Outbound Port 80" -Direction Outbound -LocalPort 80 -Protocol TCP -Action Block

It is sometimes useful.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
