Yes,you can boot straight to the desktop in both Windows 8 CP and Windows 8 RP. If you have Classic Shell installed the latest version now boot straight to the desktop. By passing the Metro start screen and so does Start Menu 7. And both software give you the Windows XP and Windows 7 start button and start menu on Windows 8.
So you don't need to do any hacks to boot straight to the desktop. Andrea Borman.
