Following the announcement of Windows 8 being released on Microsoft Connect, our Russian partners over at WinReview have managed to get their hands on the build and have posted step-by-step installation screenshots.

As you can see, the Metro UI look is being displayed even in the install-process. The OS was installed in under 20 minutes. It should be noted that it was impossible to install in VMWare.
