Incidentally, the security improvements they have added, IE settings as Antonye is finding out about, and changes to the personal firewall have stopped some application from working as they do normally.
Great from a security point of view but for the average user who isn't aware of which tcp or udp ports their app uses to communicate on it's a bit of a sh*tter - just be careful. When you install it make sure you choose the option to backup the files so you can roll it back if you need to!!!
