If the Windows 8 keynote video today wasn’t enough to satiate your Windows 8 curiosities, you can download the developer preview and install it now to check it out.
You can grab it in both 32-bit and 64-bit flavours, or the 64-bit version along with developer tools. The developer tools version requires a clean install, but if you have a Windows Vista or 7 installation on your machine, you can keep accounts, files and settings with a new installation. Windows XP users can upgrade and keep their accounts and files only. That said, we don’t really recommend installing this over your existing copy of Windows, as it’ll likely have a few quirks this early on in the preview. Hit the link below to check it out.
