So I've been taught that Present Perfect Progressive is sometimes used to emphasize the continuity of an action, as an explanation or an excuse:
I'm so tired because I've been running for two hours.
Present Perfect Progressive is also used to make excuses with an apology. (https://presentsimpleesl.wordpress.com/tag/present-perfect-continuous/)
I’m sorry I haven’t called you, I haven’t been feeling well lately.
So I wonder whether we can use Present Perfect Progressive to demand an explanation/excuse for something? I've only seen it in Present Perfect Simple, not Progressive, so is this possible?
What have you done to my computer? Why can't I turn it on now? (I see this one a lot).
