Just download the Consumer Preview Setup exe from the page linked below, and it will decide which version of Windows 8 is right for your system. It’ll tell you which of your apps are compatible with Windows 8 (if you want to upgrade your current system), grab you a product key, and download any tools you may need to create an ISO or bootable flash drive. If you prefer, though, you can just grab a regular old ISO image here, in both 32-bit and 64-bit flavors.
