Well,.. after some test with Windows 8 ,.. I certain to remove the “nice” Metro interface.
Windows 8 Developer’s Preview build has a registry key you could edit;
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer
Change RPEnabled the Value Data from 1 to zero.
But this is only valid in Windows 8 Developer’s Preview build of the operating system. Is there a way to get the old-style (Classic) Start Menu back in the Windows 8 Consumer Preview? The answer for now comes in the form of a tool called ViStart, a tool initially developed to give Windows XP a Windows Vista/7 style Start Menu.
Note: If you are going to install ViStart, be careful during the install process because it offers you third-party programs (Babylon toolbar and Registry Cleaner Pro) that you might not want to install. Install the program and the familiar Start Button (or orb) is back. However, there’s a problem because the button overlaps with the Taskbar.
