微软官方揭秘 Windows Vista SP1 未来实际更新内容

Vista之家（www.vista123.com）：微软官方揭秘 Windows Vista SP1 未来实际更新内容，

——中文翻译由Vista之家转自上方文Q

　　在透露了Vista SP1的测试版和正式版发布日期后，微软还与我们分享了第一个补丁包的具体更新情况。

　　不过首先，我们先说一下组策略管理控制台(GPMC)。相信这是个大家都非常喜欢的系统配置工具，不过安装了Vista SP1测试版的尝鲜用户可能会发现它失踪了。微软今天对此做出了解释，称由于管理员的普遍需求，Vista SP1在安装的同时会把GPMC删掉，而输入gpedit.msc后默认启动的将是本地组策略。

　　借着强调一下，Vista SP1不会在用户账户控制(UAC)上大动干戈。尽管用户对此非议颇多，但微软只会降低窗口的弹出几率，而不会做出其他变动。当然，Vista SP1会带来DirectX 10.1我们早已知晓。

　　总的来说，Vista SP1的升级内容可以分为三个方面：一是质量改进，包括可靠性、安全性和性能；二是管理技术改善，比如BitLocker加密；三是对新技术提供支持，诸如EFI接口、ExFAT文件格式等等。详细如下：

1、安全性改进

　　●让安全软件厂商更安全地与Windows安全中心协调通信。

　　●新的API接口可以让第三方安全和恶意软件防护程序介入Vista x64的内核安全防护层次并协同工作，并协调与Vista安全中心的关系。

　　●允许对远程桌面协议(RDP)文件进行签名，从而提高运行远程应用(RemoteApp)程序和桌面时的安全性，比为客户提供不同的体验。

　　●增加椭圆曲线加密法(ECC)伪随机数生成器(RPNG)。

　　●增强BitLocker驱动器加密(BDE)，加入一种新的复合因素验证方法，包括一个由可信赖执行模块(TPM)保护的密钥(存储在U盘中)和一个用户生成的PIN码。

2、可靠性修正

　　●改进新显卡在某些特定情况和配置下与Vista的兼容性、稳定性。

　　●改进笔记本试用外置显示器时的稳定性。

　　●改进网络配置中的系统稳定性。

　　●改进从XP升级而来的系统稳定性。

　　●提高大批打印机驱动程序的兼容性。

　　●提高进入休眠、从休眠中恢复后的可靠性和性能。

3、性能提升

　　●改进文件复制、移动、解压缩文件的速度。

　　●缩短休眠、恢复所需时间。

　　●改进加入域的PC在脱离域进行操作时的性能，打开文件对话框时不会再有长时间延迟。

　　●改进IE7的性能，降低CPU占用率，加速JavaScript脚本。

　　●在某些笔记本上不再频繁刷新屏幕，从而降低CPU占用率，延长电池续航时间。

　　●改善登陆体验，按下Ctrl+Alt+Del并显示密码对话框时不再偶尔出现长达10秒钟的延迟。

　　●降低浏览网络共享文件所消耗的带宽，提高速度。

4、管理体验改变

　　●除了C盘，BitLocker技术可以对额外的本地卷进行加密，比如D盘、E盘等等。

　　●解决Windows终端服务下的本地打印机问题。

　　●网络诊断工具可以帮助用户解决绝大部分常见的文件共享问题。

　　●管理员可以控制对哪些卷进行磁盘碎片整理。

　　●卸载组策略管理控制台，gpedit.msc默认启动本地组策略，管理员还可以自己加入额外的组策略对象(GPO)或者独立的设置选项，以及搜索特定设置。

5、新硬件和标准支持

　　●支持闪存和消费设备试用的ExFAT文件系统。

　　●支持Secure Digital Advanced Direct Memory Access(SDDMA)技术，适应SD HOST控制器，改善传输性能、降低CPU占用率。

　　●x64版本可以通过可扩展固件界面(EPI)启动。目前Vista支持以下三种网络启动方式：x86上的Windows部署服务、x64上的BIOS、IA-64上的EFI。Vista SP1会加入x64 EFI的网络启动支持。

　　●引入DirectX3D 10.1，增加一些API和特性，改进3D应用程序，更好地发挥新一代Direct3D图形硬件的优势。

　　●引入安全套接字隧道协议(SSTP)，是路由与远程访问服务(RRAS)平台的一部分，全面支持虚拟个人网络(VPN)远程访问，可以穿过网络地址转换(NAT)、网关和防火墙，同时不会影响现有其他协议。

 Windows Vista SP1定于9月中旬面向1-1.5万名测试人员发布第一个公开测试版，2008年第一季度正式推出。

Security Improvements

Provides security software vendors a more secure way to communicate with Windows Security Center.

Includes application programming interfaces (APIs) by which third-party security and malicious software detection applications can work with kernel patch protection on x64 versions of Windows Vista. These APIs help ISVs develop software that extends the functionality of the Windows kernel on x64 computers without disabling or weakening the protection offered by kernel patch protection.

Improves the security of running RemoteApp programs and desktops by allowing Remote Desktop
Protocol (RDP) files to be signed. Customers can differentiate user experiences based on publisher
identity.

Adds an Elliptical Curve Cryptography (ECC) pseudo-random number generator (PRNG) to the list of available PRNGs in Windows Vista.

Enhances BitLocker Drive Encryption (BDE) to offer an additional multifactor authentication method that combines a key protected by the Trusted Platform Module (TPM) with a Startup key stored on a USB storage device and a user-generated personal identification number (PIN).

Reliability Fixes

Improved reliability and compatibility of Windows Vista when used with newer graphics cards in several specific scenarios and configurations.

Improved reliability when working with external displays on a laptop.

Improved Windows Vista reliability in networking configuration scenarios.

Improved reliability of systems that were upgraded from Windows XP to Windows Vista.

Increased compatibility with many printer drivers.

Increased reliability and performance of Windows Vista when entering sleep and resuming from sleep.

Performance Improvements

Improves the speed of copying and extracting files.

Improves the time to become active from Hibernate and Resume modes.

Improves the performance of domain-joined PCs when operating off the domain; in the current release version of Windows Vista, users would experience long delays when opening the File dialog box.

Improves performance of Windows Internet Explorer 7 in Windows Vista, reducing CPU utilization and speeding JavaScript parsing.

Improves battery life by reducing CPU utilization by not redrawing the screen as frequently, on certain computers.

Improves the logon experience by removing the occasional 10-second delay between pressing CTRL-ALT-DEL and the password prompt displaying.

Addresses an issue in the current version of Windows Vista that makes browsing network file shares consume significant bandwidth and not perform as fast as expected.

Administration Experience Changes

BitLocker Drive Encryption encrypts extra local volumes. For example, instead of encrypting only drive C, customers can also encrypt drive D, E, and so on.

Addresses problems with printing to local printers from a Windows Terminal Services session.

The Network Diagnostics tool will help customers solve the most common file sharing problems, in addition to the basic problems that it already diagnoses.

Administrators can control the volumes on which to run Disk Defragmenter.

The service pack will uninstall the Group Policy Management Console (GPMC) and GPEdit.msc will edit local Group Policy by default. In the SP1 timeframe, administrators can download an out-of-band release that will give them the ability to add comments to Group Policy Objects (GPOs) or individual settings and search for specific settings.

Support for Emerging Hardware and Standards

In the future, flash memory storage and consumer devices will use the exFAT file system. Windows Vista SP1 adds support for this file system to Windows Vista.

The service pack will include support for Secure Digital (SD) Advanced Direct Memory Access (DMA), which will be on compliant SD host controllers soon, to improve transfer performance and decrease CPU utilization.

x64 PCs can boot using the EFI. Windows Vista currently supports network boot by using Windows Deployment Services for x86, a PC's basic input/output system (BIOS) for x64 PCs, and EFI for IA-64 PCs. Windows Vista SP1 will add support for network boot by using x64 EFI.

The service pack will add support for Direct3D 10.1, adding application programming interfaces (APIs) and features that enable 3-D applications, so game developers can better take advantage of a new generation of Direct3D graphics hardware.

The Secure Socket Tunneling Protocol (SSTP) is a remote access tunneling protocol that will be part of the Routing and Remote Access Service (RRAS) platform. This protocol helps provide full-network virtual private network (VPN) remote access connections without challenges that other protocols face when traversing NATs, Web proxies, and firewalls. Windows Vista SP1 will include support for SSTP.
