@bshand To answer your question, how to defer updates, it depends on the version of Windows 10 you are running. Here is a pretty good article that covers the basics. But you have to remember that upgrades are different from security patches and Home is different from Pro.
I'm running Pro and have more options than my daughters laptop running Home.
For the Pro user you can set the update to the Semi-Annual Channel which means it has more testing.
Feature updates can be set for updates to occur any day during a full year (1-365).
Security updates can be set for a month delay (1-30).
