No, it's technically the same, but from a usability standpoint this
is entirely different.

In your examples a user makes an educated and competent change, the
user acted on his own behalf.

When you pop up a dialogue and ask the user for something you
better have a) a good reason, b) good defaults, c) give thorough
guidance and explanation and d) offer a way to roll back the
changes made.

Or you can kiss your users good bye.

Raskin's Humane Interface is a good starting point.
