我应该禁用传递优化(Delivery Optimization)吗？
交付(Delivery)优化是一项内置的Windows功能，旨在确保您的Windows PC 从本地网络上的其他PC 下载Windows更新和应用程序，而不是使用 Internet。它允许Windows 10 与同一本地网络上的其他 PC 共享数据，这对于点对点更新非常有用。
So should you disable delivery optimization in Windows? Yes, you could safely disable it!
当您禁用传递优化时，您对恶意软件的保护将减少，并且某些功能可能无法正常运行。例如，如果您在禁用交付优化后拔下以太网电缆， (Ethernet)OneDrive将无法同步您的文件。
您可能已经注意到，在您的Windows中默认启用传递优化(Delivery Optimization)。这有助于减少从另一台计算机下载应用程序或与您共享的任何文件所需的时间。
但是，在某些情况下，此功能可能会导致 Windows 功能出现问题，例如互联网连接速度慢或从网络上的另一台计算机下载文件时出现性能问题。如果您遇到这些类型的问题，您应该禁用计算机上的传递优化(Delivery Optimization)选项。

Should I disable Delivery Optimization?
Delivery optimization is a built-in Windows feature that is designed to ensure your Windows PC downloads Windows updates and apps from other PCs on your local network, instead of using the internet. It allows Windows 10 to share data with other PCs on the same local network, which can be useful for peer-to-peer updates.
So should you disable delivery optimization in Windows? Yes, you could safely disable it!
When you disable delivery optimization, you will have less protection against malware, and some features may not function properly. For example, if you unplug your Ethernet cable after disabling delivery optimization, OneDrive will not be able to sync your files.
You might have noticed that Delivery Optimization is on by default in your Windows. This can help reduce the amount of time it takes to download an app or any file that is shared with you from another computer.
However, there may be instances where this feature can cause problems with how Windows functions, such as a slow internet connection or performance issues while downloading files from another computer on the network. If you’re encountering these types of issues, you should disable the Delivery Optimization option on your computer.
