功能特色
1、为您的操作系统创建脱机更新脚本
该应用程序专注于功能而非外观，具有简单的界面，仅包含一些专用于自定义下载操作的选项。
它支持各种版本的Windows操作系统，即Server 2003，XP，Visa，Server 2008,2008 R2，Server 2012,7,8和8.1。至于Office套件，它可以下载各种语言的2007,2010或2013版本的最新更新。
由于微软将停止支持某些版本（今年的Windows XP和Office 2003），WSUS离线更新将把它们视为旧版产品，将其从兼容版本列表中删除。
2、获取各种Windows组件的更新
该应用程序使您可以选择所需的操作系统，体系结构类型和语言（因为大多数更新包是多语言的）。您可以指示它在下载的软件包中包含可用的Service Pack，Microsoft Security Essentials的更新版本，C ++运行时库，.NET Framework和Windows Defender病毒定义。
创建安装脚本，然后可以在任何计算机上部署该脚本。或者，您可以将应用程序设置为生成包含所有抓取文件的ISO文件，或将所有更新复制到特定位置。
3、一种仅适用于离线系统的更新方法
WSUS离线更新可以方便地下载未连接到Internet的计算机的更新包，允许在脱机模式下进行系统更新。如果您安装了全新的Windows副本或返回到以前正在运行的还原点，它也可以证明是有用的，从而节省了获取所有更新所需的时间。
但是，为了确保您始终拥有最新的修补程序，您必须更频繁地使用它。因此，对于具有活动Internet连接的计算机，使用标准更新方法更加方便。
