New releases of IE are categorised by MS as "critical" updates (ostenstibly for security reasons), so if you have automatic updates switched on (and despite you saying they're not, it looks like they are) to even the basic level, you'll get them.
Tone: This is normal. If you don't like waiting when turning on your machine of a morning, suggest you disable automatic updates and only get reminders (or "download but don't install"). Then you can install & restart when you have the time to do so.
