That is why everyone should have a good firewall running... 11 days is MORE than enough time to patch yourself... Anyone running a server and any home poweruser should be checking http://windowsupdate.microsoft.com at LEAST once every 2 days... If you are running a server, you should also automate it...

Also, I think most of us here hear of vuln's the day they come out, and we hurridly download the patch for it if we are using the affected OS...

The bad guys finding a zero day would be hell for us... If that happens, we are screwed. That's when hopefully our well configured firewall will come through for us.
