Major Windows 10 updates, including this summer's Anniversary Update and next year's Creators Update, are distributed as essentially full operating system installs. The downloads are around 4GB, and installing them performs a complete in-place upgrade to Windows.
That is set to change as Microsoft rolls out what it calls its Unified Update Platform (UUP). Major upgrades will be shipped as differential updates, where only the differences between the currently installed version and the newly installed version need to be downloaded. The company estimates that this will result in major version upgrades being around 35 percent smaller.
UUP should also make checking for updates faster, as more of the computational workload to figure out the patches that a system needs will be handled in the cloud rather than on the client.
In making this change, some differences between the Windows 10 Mobile and Windows 10 PC update process are being eliminated. Currently the desktop platform can generally upgrade from any patch level to the latest version in one shot; on mobile, sometimes multiple updates are required, with two separate download, install, and reboot processes.
End-users on stable builds of Windows won't see this change take effect until after the Creators Update; the client-side infrastructure necessary to support these differential updates will be a part of that release. Insiders, however, who regularly perform major version updates (as every new Insider build is installed as an in-place upgrade) will begin seeing the improvements much sooner. Mobile releases will enable UUP updating starting with today's build 14959, with the technology coming to PC builds a little later in the year, followed by Windows IoT and Windows for HoloLens. Excluded from this is Xbox, which will retain its own update process.
The visible end-user impact of UUP should be minimal; Windows Update will still look the same, and the overall patching and updating policy isn't changing. It will just be faster and use less data.
主要的Windows 10更新，包括今年夏天的周年纪念更新和明年的创作者更新，作为基本上完整的操作系统安装分发。下载大约4GB，安装它们执行完整的就地升级到Windows。
随着Microsoft推出称为其统一更新平台（UUP）的设置更改。主要升级将作为差异更新提供，其中只需要下载当前安装的版本和新安装的版本之间的差异。该公司估计，这将导致主要版本升级约35％。
UUP还应该更快地检查更新，因为更多的计算工作量来确定系统需要的补丁将在云中而不是在客户端上处理。
在进行此更改时，Windows 10 Mobile和Windows 10 PC更新过程之间的一些差异正在消除。目前桌面平台一般可以从一个补丁级别升级到最新版本;在移动，有时需要多个更新，两个单独的下载，安装和重新启动过程。
最终用户在Windows的稳定版本上将不会看到此更改在创建者更新之后生效;支持这些差异更新所需的客户端基础架构将是该版本的一部分。但是，内部人员经常执行主要版本更新（因为每个新的Insider内部版本都作为就地升级安装）将很快开始看到改进。移动版本将启用UUP更新，从今天的构建14959开始，该技术在今年晚些时候到PC构建，其次是Windows IoT和Windows HoloLens。从中排除的是Xbox，它将保留自己的更新过程。
UUP的可见的最终用户影响应该是最小的; Windows Update仍将看起来相同，并且整体修补和更新策略不会更改。它只会更快，使用更少的数据。
