Fair enough.
But like I said... there are huge amounts of time when you are
not sitting at your computer.
Most people sleep for 8 hours. And most people are at work for 8 hours.
So that's 16 hours,
every day, that your home computer is just sitting there behind an empty chair.
And it's a similar story for work computers, too. Think of all the time your work computer is sitting alone in the office while you're at home.
Let's say you work in an office from 8am-6pm. Well... 6pm-8am is wide open for your work computer to do its updating magic.
I dunno... I hear people slam Windows because of "constant updates" and/or "interruptions in the middle of work"
But it's not that bad. Like you said... small Defender updates happen quickly and don't require a reboot. But sometimes there is a bigger update that might take a while. Maybe once a month after a Patch Tuesday.
It's manageable.
Of course if you keep your computer turned off or you keep your laptop in its bag on weekend... then you've got quite a surprise waiting for you the next time you start it up.
But if updates are a part of our lives (they are!) then we'll have to adapt.
