Windows 即服务是 Windows 10 版本中引入的一个新概念。Windows as a service is a new concept, introduced with the release of Windows 10. 尽管提供了一组广泛文档介绍所有细节和细微差别,此处还提供了最重要概念的快速指南。While an extensive set of documentation is available explaining all the specifics and nuances, here is a quick guide to the most important concepts.


某些新术语已引入为 Windows 即服务的一部分,因此您应该知道这些术语的含义。Some new terms have been introduced as part of Windows as a service, so you should know what these terms mean.

  • 功能更新每年3月和9月发布两次。Feature updates are released twice per year, around March and September. 顾名思义,它们将向 Windows 10 添加新功能,与以前每 3-5 年发布一次的 Windows 版本相比,它提供的区块大小较小。As the name suggests, these will add new features to Windows 10, delivered in bite-sized chunks compared to the previous practice of Windows releases every 3-5 years.
  • 质量更新提供安全修补程序和非安全修补程序。Quality updates deliver both security and non-security fixes. 它们通常在每个月的第二个星期二发布,尽管它们可以随时发布。They are typically released on the second Tuesday of each month, though they can be released at any time. 质量更新包括安全更新、关键更新、服务堆栈更新和驱动程序更新。Quality updates include security updates, critical updates, servicing stack updates, and driver updates. 质量更新是累积性的,因此安装最新的质量更新足以获取特定 Windows 10 功能更新的所有可用修复。Quality updates are cumulative, so installing the latest quality update is sufficient to get all the available fixes for a specific Windows 10 feature update. "服务堆栈" 是安装其他更新的代码,因此它们对于保持最新很重要。The "servicing stack" is the code that installs other updates, so they are important to keep current. 有关详细信息,请参阅处理堆栈更新For more information, see Servicing stack updates.
  • Insider Preview 版本在开发将随附在下一个功能更新中的功能期间提供,允许组织验证新功能以及与现有应用和基础结构的兼容性,从而就遇到的任何问题向 Microsoft 提供反馈。Insider Preview builds are made available during the development of the features that will be shipped in the next feature update, enabling organizations to validate new features as well as compatibility with existing apps and infrastructure, providing feedback to Microsoft on any issues encountered.
  • 服务渠道允许组织选择部署新功能的时间。Servicing channels allow organizations to choose when to deploy new features.
    • 半年频道每年接收两次功能更新。The Semi-Annual Channel receives feature updates twice per year.
    • 仅用于控制医疗设备或 ATM 机等专用设备(通常不运行 Office)的 Long Term Servicing Channel,大概每两到三年接收一次新功能发布。The Long Term Servicing Channel, which is designed to be used only for specialized devices (which typically don't run Office) such as those that control medical equipment or ATM machines, receives new feature releases every two to three years.
  • 部署圈是用于最初试点随后广泛部署组织中的每个功能更新的设备组。Deployment rings are groups of devices used to initially pilot, and then to broadly deploy, each feature update in an organization.

关键概念Key Concepts

Windows 10 通过每年两次的功能更新发布获得新功能。Windows 10 gains new functionality with twice-per-year feature update releases. 最初,组织将使用这些功能更新发布进行试点部署,以确保与现有应用和基础结构兼容。Initially, organizations will use these feature update releases for pilot deployments to ensure compatibility with existing apps and infrastructure. 在每个半年度频道发布时,我们建议立即开始部署,立即开始部署到选择用于早期采纳(定向验证)的设备,并按您的意愿提升到完全部署。With each Semi-Annual Channel release, we recommend beginning deployment right away to devices selected for early adoption (targeted validation) and ramp up to full deployment at your discretion.

所有版本的 Windows 10 都有18个月的所有版本的服务-这些更新提供了版本的安全和功能更新。All releases of Windows 10 have 18 months of servicing for all editions--these updates provide security and feature updates for the release. 运行企业版和教育版的客户对于特定的 Windows 10 版本有一个额外的12个月的服务,从最初版本中总共30个月。Customers running Enterprise and Education editions have an additional 12 months of servicing for specific Windows 10 releases, for a total of 30 months from initial release. 这些版本包括适用于 Windows 10 版本1607和更高版本的企业版和教育版。These versions include Enterprise and Education editions for Windows 10, versions 1607 and later. 从2018年10月起开始,所有半年度频道发布在9月/10 月的时间段内还将提供额外的12个月的服务,在初始版本中总共30个月。Starting in October 2018, all Semi-Annual Channel releases in the September/October timeframe will also have the additional 12 months of servicing for a total of 30 months from the initial release. 在3月/4 月的时间内发布的半年度频道版本将继续拥有18个月的生命周期。The Semi-Annual Channel versions released in March/April timeframe will continue to have an 18-month lifecycle.

Windows 10 企业版 LTSB 是单独的 Long Term Servicing Channel 版本。Windows 10 Enterprise LTSB is a separate Long Term Servicing Channel version. 每个版本的总支持期限为 10 年(五年标准支持、五年外延支持)。Each release is supported for a total of 10 years (five years standard support, five years extended support). 预计大约每三年提供新版本。New releases are expected about every three years.

保持最新状态Staying up to date

使 Windows 10 保持最新状态的过程涉及部署功能更新,在发布后的适当时间部署。The process for keeping Windows 10 up to date involves deploying a feature update, at an appropriate time after its release. 各种管理和更新工具(如 Windows 更新、适用于企业的 Windows 更新、Windows Server Update Services、Microsoft 终结点配置管理器和第三方产品)可用于帮助解决此过程。A variety of management and update tools such as Windows Update, Windows Update for Business, Windows Server Update Services, Microsoft Endpoint Configuration Manager, and third-party products) can be used to help with this process. 升级准备情况(可用于简化 Windows 升级项目的免费工具)是帮助的另一个重要工具。Upgrade Readiness, a free tool to streamline Windows upgrade projects, is another important tool to help.

由于桌面应用和 Web 应用都与 Windows 10 出色兼容,因此不需要进行大量高级测试。Because app compatibility, both for desktop apps and web apps, is outstanding with Windows 10, extensive advanced testing isn’t required. 仅需要对业务关键应用进行测试,其余应用通过一系列试点部署圈进行验证。Instead, only business-critical apps need to be tested, with the remaining apps validated through a series of pilot deployment rings. 在这些试点部署验证大部分应用后,可以开始广泛部署。Once these pilot deployments have validated most apps, broad deployment can begin.

针对每个新功能更新重复此过程,每年两次。This process repeats with each new feature update, twice per year. 与旧的三到五年 Windows 版本周期的必要大项目相比,这些部署项目较小。These are small deployment projects, compared to the big projects that were necessary with the old three-to-five-year Windows release cycles.

其他技术(例如对等分发工具 BranchCache 和传递优化)有助于分发功能更新安装文件。Additional technologies such as BranchCache and Delivery Optimization, both peer-to-peer distribution tools, can help with the distribution of the feature update installation files.
