A large percentage of non-tech-savvy people seem to hate upgrading.

For them, an update just slows them down or leads to confusing changes. What they already have "works fine."

The difference between "auto update" and "an option to update" is huge.

I didn't mean to imply it wasn't a huge difference. Just correcting someone from above..

It's free, but, yeah, I had to open the Windows Store or whatever and actually make it update. It did not show up in the Windows Update list (not even in the "Suggested Updates").
