Well, don't be mad at microsoft, they told you to not use the beta in a production enviroment because it's not fully active!
As far as GPOs go.. any moronic hacker can bypass those suckers. It's even easier then asking for someones credit card number in AOL chatrooms lol. If you are a fresh user on a workstation, the instant you log in and push enter after putting your password in, unplug the network cable til you get to the desktop. GPO lockdown what??? Well, until a refresh happens, but it will give you the chance to make any system settings changes you wish, and they stick.
