1. Automatically install updates (recommended)
2. Check for updates but let you choose to install them
You would think I'd choose option 2, since I don't want updates, but I tried that, and I got a popup several times a day saying INSTALL UPDATE NOW OR LATER—no way to say "No I don't !%$@ want to update!" ... so after putting up with that for a while I changed to option 1 to avoid the neverending update popups. Not at all what I want though. Talk about a dark pattern. "let you choose to install them" indeed! Not "choose whether to install" but "bombard you with update popups until you crack and choose to install".
