交付优化^{(Delivery Optimization)}基本上是一种客户端更新服务，它在 Internet 的帮助下使用本地和非本地设备来交付Windows 更新^(updates)。该服务结合了来自Microsoft数据中心和本地设备的数据。合并后的数据有助于以较低的带宽成本提供完整的更新，也有助于快速更新^(updates)。我们已经看到了如何通过设置^(Settings)关闭传递优化。在这篇文章中，我们将向您展示如何在 Windows 10 中通过组策略^{( Group Policy )}或注册表编辑器^{( Registry Editor)}禁用传递优化。^{(Disable Delivery Optimization)}

通过组策略^{(Group Policy)}禁用传递优化^{(Delivery Optimization)}

交付优化^{(Delivery Optimization)}本质上是Windows 10中一个非常有用的功能。但是，一些用户可能会遇到一般 PC 性能低下、high disk usage, and/or high CPU usage。在这种情况下，禁用此服务可能会很好。

请执行下列操作：

• 按Windows key + R调用“运行”对话框。
• 在 Run 对话框中键入gpedit.msc并按 Enter打开 Group Policy Editor^{(open Group Policy Editor)}。
• 在本地组策略编辑器^{(Local Group Policy Editor)}中，使用左窗格导航到以下路径：

Computer Configuration > Administrative Templates > Windows Components > Delivery Optimization
