The idea was you would shut it down when you were done with using it, so taking that moment to update wouldn't be a problem. You're not using it, so now it's my turn. Problem is those people who never turn off their computer.,(reply>), @Rob Laquiere Yea, that works great for people that leave their computers on 24/7 but my acceptable hours would be when my computer is off. Turns out computers don't like doing things when they're off, so they catch up when they're on.,(reply>), There is a setting that instructs your computer when the acceptable hours for updates and restarts are.  My computer only auto-updates during the hours I set.  I didn't know most users did not know about this function.<br><br>Maybe its because most users skip through most of their computer setup process, and then wonder why the default settings don't align with their usage profile.,(reply>), user: working on something that took them 5 hours and forgot to save<br><br>windows: &gt;:),(reply>), Me on Ubuntu: "That never happens...
