I have a question about the WSA firewall.
It is declared that WSA firewall need windows firewall to work, it is an added protection.
However, when I set the WSA firewall with block one process called "iexplorer.exe" which is ie browser.
And then I set the windows firewall to allow the connection for "iexplorer.exe".
The result is blocking the internet for browser.
Further more when I turned off the windows firewall, WSA pops out an dialog to warn me.
I clicked "No" for not activate the windows firewall, and WSA firewall is still open.
In this situation, I still can't use IE to surf the internet.
The question is, is WSA firewall independent with windows firewall?
If no, why suggest to open windows firewall?
If yes, why I turned off the windows firewall, and WSA firewall still works?
I check the previous discussions as well, but it didn't mention about the "independent" or "priority"
If I turned off the windows firewall( because setting windows firewall rule is so inconvenient)
Only rely on WSA firewall, what is the risk for outbound and inbound respectively?

Foremost there is necessary to understand that the Windows firewall is very powerfull for inbound connections. Yes you can also set outbound rules but it is not so simple task. That's where WSA firewall stands up and provides strong protection. Therefore you shouldn't rely just on the Windows firewall or WSA firewall. They needs to be run together unless you are using a thrid party firewall. Having them run along you have very strong firewall where Windows controls inbound and WSA outbound connections.
Here's what the leader of development team said:
"The only "help" that WSA receives from the Windows firewall is inbound protection. There is only really one way to write an inbound firewall and the Windows firewall covers it off perfectly fine. No third party firewall is going to be more effective so we instead put our focus in other areas where we could actually make new innovations."
