Today’s Windows 10 Insider Preview Build 18917 looks like a major release, introducing download throttling options along with making Windows Subsystem for Linux 2 official. Here are the complete details: > We’ve heard from our users with very low connection speeds that setting download throttling as a percentage of available bandwidth isn’t providing enough relief in reducing the impact on their network. That’s why we’ve added a new option to throttle the bandwidth used by Delivery Optimization as an absolute value. You can set this separately for Foreground downloads (downloads that you initiate from Windows Store for example) or background downloads. This option already exists for IT Pros who use Group Policies or MDM policies to configure Delivery Optimization. In this build, we’ve made it easier to set via the settings page.
