Under normal circumstances, this might not be that big a deal, but these are not normal times. With so many people working from home right now, getting a big update in the middle of trying to get something done for work can be a genuine pain.
Microsoft has heard the growing chorus of user complaints and has done something about that. Since the Fall Creators Update (Windows 10, 1709), the OS includes a little advertised Delivery Optimization feature that allows users to specify a percentage of the available bandwidth to use when installing updates.
To activate and configure it, here's all you need to do:
Doing the above allows you to adjust the sliders for both of those options. Just set the sliders to indicate the amount of bandwidth you want to allocate for that purpose, and when you have them where you want them, close the settings window and you're all set.
While it does take a bit of hoop jumping to actually get to the screen, kudos to Microsoft for making the option available.
