Notice the Start Button has returned? I tried to use the OS without a Start Button/Menu replacement, but I just couldn't get to grips with it. I downloaded Pokki which is a free Windows 8 Start Menu replacement. It's really good. Very customisable indeed. I've several Windows 8 Start Menu replacements and Pokki has been favourite. It's the easiest to install and uninstall. You can download it here
