After all you can only auto update microsoft and store apps. Other apps will either handle updates themselves probably with an annoying UAC prompt and possibly at inconvenient times when you actually want to use the apps. Some have processes that constantly sit in the background sucking up your resources to pop up annoying prompts to update application foo during which you must watch for them changing your browser preferences and installing adware. Others you will simply have to go to their website and download an exe or msi.
Meanwhile you are missing the fact that people don't want to avoid automatic updates to fix security holes. They want to avoid updating to the next undesirable update foisted on the users before its ready and much to peoples annoyance. Example the windows 8 UI change.
Unbelievably staying on an older still supported platform until you are ready to update is a feature you have to pay money for!
Lest you misunderstand I'm not talking about clinging to windows xp till they claw it from your cold dead hands 3 years after end of life I'm talking about the future equivalent of staying with windows 7 and upgrading to windows 10 because 8 sucks.
