My wife does this. One time a support scammer called trying to get her to install malware. It went something like this:

"Ok. Please press the Windows key"

"Ok (long pause)"

"Did you press it?"

"Yes"

"What happened?"

"Nothing happened"

"Try again."

"Ok... Nothing. Does it matter that I don't have a windows?"

"Oh you have Mac?"

"No, I have Ubuntu"

"Ok, what version?"

"I don't know!? You're the computer person. Why don't you know?!"

The best part is that she was sitting on the couch the whole time.
