First reaction, MSFT didn’t pack anything new from the previous pre-beta version. Yes, ofcourse, the Beta Fish on the loading !
Used the usual tested route of installing Windows 8 on a Oracle virtual Box with 2GB ram to spare and VHD spacing 20GB. The installation and set up was a breeze.
The Zoom button on the bottom right portion to do context zooming and Charms when hover to bottom right is another addition. Initial 15-20 mins of play has not revealed any new feature. Will keep exploring more on the AppLocker and native-Hyper-V support.
