The alpha build of Windows 8 has been leaked onto the world wide web. The previews are available here: http://dev.windows.com/, later today. They are incomplete developer builds, so do not expect to be able to install these and run your business or other critical applications, but they are perfect for testing out the new features of Windows 8 and giving valuable feedback to Microsoft. There is no activation or product key required to install this version of Windows, but I am not sure if you can keep these installed and essentially get a free installation of Windows 8 out of this. But Windows was going to be leaked anyway and Microsoft are taking a leaf out of the Linux book and putting up alpha builds on the web for people to try before they commit to downloading the full release. Hopefully, with all the feedback they will receive from those testing Windows they will not make another Windows Vista or Windows Millennium Edition. The new Metro interface is not very popular, I would hope that they would keep the Windows Classic interface that is a good alternative to the Aero styled UI seen in Vista and Windows 7.

How to install the Windows Developer Preview from an ISO image.
The Windows Developer Preview is delivered as an .iso image that must be converted into installation media stored on a DVD or a USB flash drive. On Windows 7, the easiest way to convert this file is to use Windows Disc Image Burner. On Windows XP and Windows Vista, a third-party program is required to convert an .iso file into installable media—and DVD burning software often includes this ability.
Note: The .iso file that has the developer tools requires a large capacity DVD called a DVD-9, as well as a DVD burner that can handle dual-layer (DL) DVDs. Most modern burners should be able to handle this format.
