Check windows task scheduler for a task called "CH Aurora". If it exists, you can delete it (and autostart in Aurora should be unchecked).
//edit: I was able to reproduce the issue where Aurora doesn't autostart in 1.7.1, should be fixed with 1.7.2

Following your advice I deleted the CH Aurora entry in the task scheduler...but...the Aurora's autostart box is uncheckable, clicking do not affect the state, it's stays on permanently.
