My favourite kind of updates are those that happen on a Friday afternoon where you push all the buttons you think you have to, and it looks like it's getting on with it, so you switch the monitor off and go home for the weekend, then when you come back in on Monday there's another popup that says "you have to push this button for no reason before I'll install these updates" and then you have to sit there watching it update because it's sat there for the entire fucking weekend waiting for you to push that stupid pointless button.
I wish there was a checkbox that says "Complete updates without requiring any further user input. Wanna reboot? Reboot. Wanna download some shit? Download some shit. Wanna start installing some shit? Install some shit. Wanna repeat over and over? Repeat over and over" or something like that.
