I will confirm Aura's statement. Other than for third-party drivers, which often get submitted to Microsoft for inclusion in Windows Updates, I have no third-party software, including Firefox, Chrome, CCleaner, and the list goes on that get updated via Windows Updates. When each was installed I was presented with an option as to whether I wanted to "check for updates" and I always set that to yes. Updates to software are generally not done "just for fun" these days.
The computer you describe is the perfect example of why I strongly encourage my clients to keep Windows Update set to either fully automatic or "download but let me choose when/what to install." Full automatic is problematic for those who leave their computers on constantly and may have "active work" that they've walked away from in several programs. Even though most programs now do automatic incremental saves so that changes can be recovered if the machine goes down for any reason, not all do. It's a nasty surprise if automatic updates do a system restart when you don't expect it.
The latest versions of Chrome are set up to automatically update when new versions are available, but they don't restart by themselves. The "pancake button" at the upper right will change color when an update becomes available and it wants you to restart. It starts out green when the update is just released, turns yellow if you don't restart within a couple of days, and turns red if you still haven't restarted for a few days after that.
