Can’t get enough of Windows 8? Then here’s a treat. A copy of the Windows 8 Developer Preview is now available for download here and you don’t need to activate it. Available in both x86 and x64 versions, this build works on the same requirements that run Vista and Windows 7. As per the other windows builds, it is recommended that you install this one on a “disposable” machine as this is pretty much a very early beta. Maybe you can verify the very fast boot time that Windows 8 promises, as seen in here.
