Mostly just when you initially install like most OSes ; browsers, office suits, game launchers, etc... My mother doesn't even notice fedora automatically installing updates when she turns her PC off. (I enabled automatic updates for her)

Even with my arch Linux install with Hyprland, most of the time I just update before I turn it off. With a terminal command but even that is just paru and my password or flatpak update. If I had kde or gnome desktop, I could set it up to auto update too.

Sometimes I don't even bother and use the computer without updating it for a couple of months or it automatically updates when I install new software.
