Dedoimedo posted a tutorial about customize Windows 7 to look and behave like Windows 8

Oh noble and benevolent me, I keep sacrificing for you, fiddling with Windows 8 that I dislike so. I've compiled this long tutorial explaining how to customize Windows 7 to look and behave like Windows 8, using free tools, utilities, configurations, and artwork, including third-party patching of the Windows theme, installation of new themes, Windows Explorer buttons, system fonts, Start menu icon, logon screen, boot splash screen, interactived tiled screen, additional changes and tweaks like sounds, colors, wallpapers, and much more. Best of all, you retain the sane functionality, and none of that stupid tiled screen nonsense. Have fun. And gimme a friggin' medal for the effort.
