There is a workaround for this Windows 10 allows you to define certain wifi networks as metered (data-capped) connections. When you do this, it effectively disables automatic updates. To do this, go to Start → Settings → Network & Internet. Then go to Advanced options:
On the next screen, turn on the “Set as metered connection” option. I’m on my work computer right now and corporate policy has this option disabled (which is why it’s grayed out in the screenshot below), but you should be able to do this on your home computer.
