The next feature version of Windows 10 that's going to release in early 2020, will allow you to control the absolute bandwidth for downloading Windows 10 updates. The new throttling option will reduce the burden in the slow network.
If you are a Windows Insider in the Fast ring, you can try this feature now with the latest preview build 18917. In this post we will discuss how to set this settings.
