How do I turn off Modern UI and get the old Start Menu back in Windows 8?

I just installed Windows 8 Consumer Preview edition and I tried to modify the RPEnabled to 0, so I can have the Windows 7 Start Menu.

After a restart, the Metro UI menu is still there. Does anyone what is causing this? This should work.

This is my favorite:

it adds the original Windows 7 startmenu back (which is still present in Win8 but disabled).

How is it possible for Windows 8 to have real start menu? Microsoft said they did remove it!

They did, but not completely. Removing start menu completely would require rearchitecting some key Windows code base and raising compatibility issues which they couldn't seemingly afford. StartIsBack reuses large portion of start menu code left, but contains a large amount of code to make as well it work as you expect and new functions too.
