Here's an interesting site for those who want to test their firewalls. It's free and very comprehensive. Yes, I know about Steve Gibson's firewall test and I use it. But I went ahead at this site because I thought there might be some difference in the returned results. Indeed, there was and I swiftly fixed it.
In addition; they offer download of a tool which prevents Windows Genuine Advantage from calling home to MS at every boot. Check it out. Hopefully, I will be able to report on the tool's efficacy by Sunday's show. Time is tight, though and I'm struggling hard to clear the decks enough to allow testing it.
