Download the Windows 8 Consumer PreviewMicrosoft has released their long-awaited Windows 8 Consumer Preview today.

The download is available, and is just a bit over 3GB as a full ISO.

We will be putting up a guide to installing the OS on your current machine in the next few hours, but for now you can download the ISO or set-up tools here.

Windows 8 is a radical departure from past Microsoft operating systems, as it uses the touch-friendly Metro UI, a whole new slew of apps, gestures and a completely overhauled browser. Underneath it all, however, consumers with Windows 7 should not expect anything too far out of the ordinary.

If anyone has any first impressions of Windows 8 before our post, please feel free to add them in the comments.
