什么是服务堆栈更新?What is a servicing stack update?

服务堆栈更新提供了服务堆栈(安装 Windows 更新的组件)的修补程序。Servicing stack updates provide fixes to the servicing stack, the component that installs Windows updates. 此外,它还包含“基于组件的服务堆栈”(CBS),该服务堆栈是 Windows 部署的几个元素的重要基础组件,例如 DISM、SFC、更改 Windows 功能或角色以及修复组件。Additionally, it contains the "component-based servicing stack" (CBS), which is a key underlying component for several elements of Windows deployment, such as DISM, SFC, changing Windows features or roles, and repairing components. CBS 是一种小型组件,通常不会每月发布更新。The CBS is a small component that typically does not have updates released every month.

为什么应安装服务堆栈更新并保持最新状态?Why should servicing stack updates be installed and kept up to date?

服务堆栈更新提高了更新过程的可靠性,从而减少在安装最新质量更新和功能更新时出现的潜在问题。Servicing stack updates improve the reliability of the update process to mitigate potential issues while installing the latest quality updates and feature updates. 如果未安装最新服务堆栈更新,则存在无法使用最新的 Microsoft 安全修补程序更新设备的风险。If you don't install the latest servicing stack update, there's a risk that your device can't be updated with the latest Microsoft security fixes.

何时发布?When are they released?

根据新问题或漏洞发布服务堆栈更新。Servicing stack update are released depending on new issues or vulnerabilities. 在极少数情况下,可能需要按需发布服务堆栈更新,以解决影响安装每月安全更新的系统的问题。In rare occasions a servicing stack update may need to be released on demand to address an issue impacting systems installing the monthly security update. 从 2018 年 11 月开始,新服务堆栈更新将被分类为“安全”,严重性分级为“严重”。Starting in November 2018 new servicing stack updates will be classified as "Security" with a severity rating of "Critical."

服务堆栈更新与累积更新之间有何区别?What's the difference between a servicing stack update and a cumulative update?

Windows 10 和 Windows Server 均使用累积更新机制,在这种情况下,可将用来提高 Windows 的质量和安全性的许多修补程序打包到单个更新中。Both Windows 10 and Windows Server use the cumulative update mechanism, in which many fixes to improve the quality and security of Windows are packaged into a single update. 每个累积更新包含所有先前更新中的更改和修补程序。Each cumulative update includes the changes and fixes from all previous updates.

服务堆栈更新必须与累积更新分开提供,因为它们修改安装 Windows 更新的组件。Servicing stack updates must ship separately from the cumulative updates because they modify the component that installs Windows updates. 服务堆栈是单独发布的,因为服务堆栈本身需要更新。The servicing stack is released separately because the servicing stack itself requires an update. 例如,累积更新 KB4284880 需要 2018 年 5 月 17 日服务堆栈更新,其中包括 Windows 更新。For example, the cumulative update KB4284880 requires the May 17, 2018 servicing stack update, which includes updates to Windows Update.

是否有任何特殊指南?Is there any special guidance?

Microsoft 建议在安装最新累积更新前,安装操作系统的最新服务堆栈更新。Microsoft recommends you install the latest servicing stack updates for your operating system before installing the latest cumulative update.

通常,改进是指不需要任何特定特殊指南的可靠性和性能改进。Typically, the improvements are reliability and performance improvements that do not require any specific special guidance. 如果有任何重大影响,将在发行说明中显示。If there is any significant impact, it will be present in the release notes.

安装说明Installation notes

  • 服务堆栈更新包含完整的服务堆栈;因此,管理员通常仅需要安装操作系统的最新服务堆栈更新。Servicing stack updates contain the full servicing stack; as a result, typically administrators only need to install the latest servicing stack update for the operating system.
  • 安装服务堆栈更新不需要重新启动设备,因此安装不应中断。Installing servicing stack update does not require restarting the device, so installation should not be disruptive.
  • 服务堆栈更新版本特定于操作系统版本(内部版本号),与质量更新非常类似。Servicing stack update releases are specific to the operating system version (build number), much like quality updates.
  • 搜索以安装最新可用的适用于 Windows 10 的服务堆栈更新Search to install latest available Servicing stack update for Windows 10.
