Not really your place to judge is it? What if they are in the middle of a long running task and the machine shuts down? Maybe it takes all day to run that process intensive task? Boom updates reboot the machine and a whole day's processing was lost. It is the users' prerogative on how they want to use their machine (poor software design choices and all) and if they don't want to take an automatic update and reboot then so be it. Or what if some people like to wait a couple weeks and see if Microsoft accidentally breaks something major with an update... pretty sure that has happened before.

In my case, I started a simulation running overnight. The next day I found that Windows had rebooted to install a patch and killed my simulation. (I'm now using a Mac.)

We're power users. We've already been burned by this, and we know how to defend against it.

That doesn't help my mom when she's writing a long letter and (rightly) expects her computer's RAM to hold the information and warn her before it does anything destructive. That doesn't help the middle-schooler who is suffering through their first 5-page essay.

Use an OS that behaves in a way I like more.

Save when convenient.

Repeat as necessary.

I prefer to use software that behaves the way I want it to, rather than modifying my own behavior to work around its shortcomings.
