Under Advanced Options there are four key areas/settings:
(1) Use this slider to choose how much bandwidth is dedicated to the downloading of updates in the background.
If your connection is 50Mbps then that means selecting 50% here would allow updates to garner 25Mbps of that connection for those related update downloads.
(2) This setting sets similar limits as (1) except it is related to the updates you are sharing to other Windows 10 PCs on the Internet.
(3) This is where you set a data limit related to the uploads from your device.
(4) This chart tracks how much of the designated data from (3) is used each month.
See the next image for minimums for these settings.
