Microsoft Corporation has released a test version of Windows 8 at its annual developer conference, hoping to stoke excitement over its new operation system.
微软公司在其年度开发者大会上发布了Windows8的测试版，希望为其新操作系统增加令人兴奋的因素。
Windows unit chief Steven Sinofsky stressed the new operation system is the first to focus on applications. It boots up in seconds and features a home page filled with colorful tiles taking the user directly into applications such as Facebook, messaging or news feeds.
Windows部门主管史蒂文-辛诺夫斯基强调，这个新的操作系统首先是基于应用软件的。它几秒钟内就能启动，它以充满多彩的平铺窗口的主页为特色，这些平铺窗口能使用户直接进入像Facebook，messaging or news feeds等这样的应用。
Analysts say the new system is consumer-orientated and intuitive but it will take time to see whether it is an iPad killer. Microsoft itself has not set a schedule publicly for release of Windows 8. Sinofsky says the process will be "driven by quality, not by a date".
分析人士表示，该新系统是以客户为中心的、直观的，但是它是否是iPad杀手还有待时间考验。微软公司自己并没有公开确定Windows8的发布时间表。辛诺夫斯基称，过程将“我们将由质量，而非日期来驱动”。
