（CSDN记者/Jimmy Gan 编译/彭一凡）洛杉矶时间10月28日上午，北京时间29日凌晨，在PDC2008第二天的会场上，微软第一次向软件开发者全面公开演示了Windows 7。Windows 7在Windows Vista的基础之上，进一步加强了对开发者操作体验的投入，使得在Windows平台上构建新的应用和服务程序变得更加容易。在大会上，微软向PDC与会者提供了Windows 7的预测试版；并且宣布，计划在明年投放一个完整的Windows 7 beta版本。
微软首席架构师Ray Ozzie说，“我们将Web中的优点融入Windows，也将Windows的优势带进网络。从PC到Web再到手机、从服务器到云端，我们的目光聚焦于如何创造下一代的用户体验，这些体验将改变我们的生活、工作和娱乐方式。”
Windows 7特性预告篇
Windows 7的设计理念是让我们每一天的工作变得更容易更高效，让用户更愿意接受新事物。 Windows 7反映了业界的一次演变过程，就是让客户和合作伙伴的反馈能够与开发过程更加紧密相连。这不仅会带来更富创造力的崭新特性，同时也保持了应用程序和设备的兼容性。对于Windows 7，微软尝试建立一个更一致、更可预测的发布计划，这样Windows的合作伙伴就可以更容易更迅捷地提供一些新性能，而这些性能是下一版本的 Windows所必须提供的。因此，当Windows 7被投放到市场时，它会具有下面几条特性：
• 按您所需要的方式工作。Windows 7将会给您带来基本性能，以及可靠性和安全性。并且它的设计完全兼容Windows Vista可以识别的硬件、应用程序和设备驱动程序。新的特性包括：保护您的隐私和数据，让PC运行更容易，以及快速的故障恢复能力。
• 让您每天工作得更快更简单。Windows 7将简化人们常用任务的操作。全新的导航条和任务条以及精简的用户界面将会使平时需要的资源变得触手可及。在家、在办公室或者在路上，PC与其他设备之间的数据共享也会变得更容易。Windows 7和Windows Live将帮助您与您最关心的人和事情紧密联系在一起，IE 8则会带给您更加快速、安全和丰富的Web体验。
• 让创造成为可能。Windows 7将会对用户与PC之间的交互方式提供多种选择。比如多触点姿态等。通过设备存储器，Windows 7使用户可以从相机、手机和打印机中能够获取到更多信息。不仅如此，它还可以让家庭音视频系统以及其他网络媒体设备的使用更加简单。您可以很方便的用它们播放音乐、看视频或者显示照片，而这些资源都存储在装有Windows的PC中。另外，Windows 7还会提供更多自定义选择来满足用户对个性化风格的需要。
为开发者提供坚实的基础
Windows 7的设计，考虑了如何提供一个坚实的平台，来开发新一代Windows解决方案。Windows 7能够让开发者更富创造性。并且它为开发极富魅力的应用程序提供了新的功能。全新的任务条、Ribbon、destinations和shell的一体化将加强所有应用的可扩展性和可用性。另外，IE 8、本地化Web服务API与联合搜索，也使开发者可以将Windows和Web服务中的优点结合在一起。
Windows和Windows Live工程团队的高级副总裁Stephen Elop说：“我们为能够在今天的PDC2008大会上向开发者发布Windows 7预测试版感到激动。基于新的计划和开发方案，我们现在拥有了一个很好的基础，它使得我们的合作伙伴可以在这个全新的Windows版本上开始学习、创造。”
据悉，除了Windows 7，PDC2008与会人员还会拿到Windows Server 2008 R2的预测试版，它是Windows Server 2008的增强版本，包括引入虚拟机、电源保护功能和构建、托管下一代应用和服务的开发特性。

Microsoft Delivers Pre-Beta Release of Windows 7 to Developers
LOS ANGELES — Oct. 28, 2008 — Today at its Professional Developers Conference 2008 (PDC2008), Microsoft Corp. rallied software developers by sharing the first full public demo of Windows 7. Windows 7 extends developers’ investments in Windows Vista and encourages the creation of new applications and services for the Windows platform. The company also delivered a pre-beta build of Windows 7 to PDC attendees and announced plans to release a full Windows 7 beta early next year.
Microsoft also demonstrated, for the first time, its new Web applications for Office, which are lightweight versions of Microsoft Office Word, Excel, PowerPoint and OneNote that are used from within standard Web browsers. The company showed how anyone can use all of the Web, phone, and PC versions of Office to edit the same rich document, switching among them seamlessly with lossless file compatibility.
“We are bringing the best of the Web to Windows, and the best of Windows to the Web,” said Ray Ozzie, chief software architect at Microsoft. “From PC to the Web to the phone, and from the server to cloud, we are focused on enabling the creation of the next generation of user experiences that change the way we live, work and play.”
Windows 7 Preview
Windows 7 is designed to make everyday tasks faster and easier, and make new things possible for end users. Windows 7 reflects an evolved approach to engineering that incorporates customer and partner feedback more closely into the development process. It will deliver innovative new features while focusing on application and device compatibility. With Windows 7, Microsoft is working to establish a more consistent and predictable release schedule so partners across the Windows ecosystem can easily and quickly build on the new capabilities Windows has to offer. When released to the market, Windows 7 will enable the following:
• Work the way you want. Windows 7 will deliver the fundamental performance, reliability and security features that people expect — and it is designed to be compatible with the same hardware, applications and device drivers as Windows Vista. New features will help protect privacy and data, make it easier to keep a PC running smoothly, and enable quicker recovery from problems.
• Make everyday tasks faster and easier. Windows 7 will streamline and simplify the tasks people do most often. Improved navigation, a new taskbar and a streamlined user interface put commonly used resources within easy reach. Sharing data across all PCs and devices will be easier at home, in the office or on the go. Windows 7 and Windows Live will help users stay connected to the people and things they care about, and Internet Explorer 8 will offer a faster, safer and more productive Web experience.
• Make new things possible. Windows 7 will offer more choice in how users interact with their PCs, such as through multitouch gestures. With Device Stage, Windows 7 enables people to get more from the devices they use most often with their PC, such as cameras, phones and printers. Windows 7 also will make it easier to use home audio-video systems and other networked media devices to play music, watch videos and display photos that reside on Windows-based PCs. And Windows 7 will offer more options than ever to customize and personalize Windows-based PCs with styles that match the user’s personality.
A Solid Foundation for Developers
Windows 7 is being designed to provide a solid platform to enable a new generation of solutions for Windows. Windows 7 will enable developers to be more productive and offers new capabilities to create more stunning applications. A new taskbar, Ribbon, destinations and shell integration enhance discoverability and usability for all applications. In addition, Internet Explorer 8, native Web services API and federated search enable developers to integrate the best of Windows and Web services.
“We are excited to be delivering a pre-beta developer release of Windows 7 today at PDC2008,” said Steven Sinofsky, senior vice president of the Windows and Windows Live Engineering Group. “With our new approach to planning and development we now have a great foundation for our partners to start learning and innovating on this exciting new version of Windows.”
In addition to Windows 7, PDC attendees received a pre-beta developer release of Windows Server 2008 R2, which will deliver many enhancements to Windows Server 2008, including live migration of virtual machines, power saving capabilities, and developer features to build and host next-generation applications and services.
