It not yet clear what method he was able to do to get the start menu back. But it's not likely to be made public because Tihiy is probably looking to offer the final version at a fee. The beta 0 is set to expire on the 25th October ( just in time to make a profit from Windows 8's release hahahah
Anyway here are some screenshots I made:
The customize menu that used to be in the taskbar property setting is wrapped in an isolated dialog box. Everything from the native start menu is there as you can see the correct right-click menu on the computer item. Even the old trick Shift+Ctrl+Right click shows the hidden "Exit Explorer" menu item.

You can get to that isolated dialog by right click on the start button and choose its setting.

The Modern UI tab allow to you to disable the hot corners. The bottom-left hot corner is disabled by default permanently.

Other goodies include straight booting into the desktop without any automated keystroke hacks. It literally boots to the desktop from a cold boot-up.
Well, what are you waiting for metrohaters =D, go grab the beta 0 over at http://www.msfn.org/...-start-is-back/
The only thing left for someone to do is to bring back Aero Glass as you can see it is absent. Only time...=D
edited: quick note, after running the registry hack, just logout and log back in. No need for a reboot.
