Code(0)
Type(8)
svchost.explorer.exe and system are part of Windows and should be made “outgoing only”. See here. As far as the codes not sure. Did you read the help file?
You mean like this ? ???

This is how the things are set on my PC.
No thats not how. Look at my screen shots in that post. Why do you have svchost as a web browser. You dont need all those rules.
Obviously he’s actually controlling the firewall Vettetech.

Not sure why you use those rules for system. I have system outright blocked, but YMMV.
On svchost, i don’t have CFP in front of me, i can’t remember if it needs FTP.
HTTP (port 80) is for updates i believe.
Thanks Vettetech, I did changed my settings with the ones you posted in the Screenshot. 
Ok good. Anything else? (R)
Unless the firewall implicit allows inbound Echo reply (Type 0, Code 0) and outbound Echo request (Type 8, Code 0), your own ping requests will be dropped. Same goes for “tracert” attempts
