This build is the first publicly available build of Windows 10. It was demoed on 2014-09-30 on a closed press conference and released to the public the next day. If you want to get this build then you can do it here. (Note: file size > 3 GB)

If you want to be able to use the reporting feature you will need a Microsoft account and your system requires at least: 1 GHz or faster processor, 1 GB or more RAM (for x86) or 2 GB or more (for x64), at least 16 GB of HD space. If you're installing this on a physical device you will also need a DirectX 9 graphics device with a WDDM driver. That said, on a physical device is not recommended. Either use a secondary PC or a virtual one. The screenshots below (to be uploaded here later) were taken in VirtualBox.
