If you want to change the Windows 8 start menu back to the Windows 7 version, here’s what you need to do:
Launch the registry editor (win+r > regedit >enter)
Drill down to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer
Double-click on RPEnabled
Change the value from 1 to (zero)
Tap enter or click OK
The change will take place immediately — just tap the Windows key on your keyboard twice to try it out (the first press will slide the Metro start screen back into view).
Once you make the change, the trademark Windows 8 start screen will no longer appear after you log in. Instead, you’ll be greeted by an interface that looks almost exactly like your existing Windows 7 desktop — the only real difference being the squared-off window borders on your applications. Whether the menu makes it as an option in the final Windows 8 release is unknown, but I’m sure Microsoft will be getting plenty of feedback about its removal.
