Microsoft has been working on several new features for Windows 10 since 9926 was released, some that are showing up in the build leaked earlier today and some that are still absent. One feature buried deep in the settings of the OS that paves the way for how future updates will be delivered to your machine has been uncovered.
In build 10036 of Windows 10, there are settings that change the location from where you receive updates to Windows 10, and apps too. As you can see from the image at the top of this post, you now have the option to have multiple sources deliver updates to your PC. More specifically, you can choose where to download the updates from, including your own local network or PCs on the Internet, and of course you can turn off this functionality.
