The way you respond to a computer update says a lot about your personality. Mayhaps it's reasonable to schedule the update in 2 hours, but it's also so much easier to just say, "NOT NOW."
The operating system should take the hint from past responses. "Look, I know you hate doing the update, but it's a great time to do it now, so just pause for a moment and just get it done. You'll be so glad when it's over."
In a few hours.
Not sure when, but definitely NOT NOW. GOD!
