微软于北京当地时间9月14日正式对公众发布了 Windows 8 的首个预览版，并将其称之为 Windows Developer Preview （以下简称：Windows 8 Dev-Pre）。这是一个适用于开发人员的预览版本，所以当你要进行体验时，请谨慎选择！

        严谨一些的话，我们应该称“Windows 8”为 Windows Next，鉴于 Build Windows 大会上都改称 Windows 8，所以我们姑且就这么叫他吧。

        目前 Windows 8 发布了三个 Windows Developer Preview 包，供开发者使用！当然也有独立的系统版本包，ITPro 也可以尝鲜。

• 1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)  
• 16 GB available hard disk space (32-bit) or 20 GB (64-bit)  
• DirectX 9 graphics device with WDDM 1.0 or higher driver  
• Taking advantage of touch input requires a screen that supports multi-touch
