There is a simple way to enable Windows 7 like menu in Windows 8. After completing the edit described below you will have two menus. The ugly Metro menu after moving your mouse to the lower left corner of the screen and pressing start icon AND THE STANDARD Windows 7 like start menu after just pressing the start key as usual :)
Open Run type regedit.exe hit Enter key to launch Registry Editor.
In the Registry Editor, navigate to
In the right pane, double-click on the entry named RPEnabled and change its value from 1 to 0 to enable the Windows 7 Start menu.
