I swear, I tried to "work" with Windows 8. In my opinion, the Startscreen is great when working with Touch enabled devices. But on desktop view, I really miss the Windows Button and/or Windows-Key function. I'm not only accustomed to it, I need it, it makes me somewhat crazy, that the Start Menu was not included in the final Version of Windows 8. And also the well known registry hacks known from the Windows 8 Betas and RCs do not work anymore.
But thanks to Stardock, primarily known for their great Windows UI customization Tools, you can get the start menu back. The Little tool is known as Start8, find the download link below. You can also try ViStart from Lee Soft. Both re-enable the classic Start-Button with all its comfort :)
