When a user installs a software update, why does the user have to answer any questions? The base/previous version is already installed and running.
If the user has asked/agreed to an update and unless there are new options or other critical user interaction required, the software should just update itself silently.
Millions of person-hours are wasted with the user answering the same questions for every update -- over and over.
Samples of stupid questions:
Agreeing to the license (didn't the user already do that?)
Does the user really want the update - duh?
Click finish to complete the update (like there is another option).
