I had fun with a similar call only much shorter. When I got the call I played along until we got the event viewer. When he asked what I saw I said nothing. He wasn't expecting that so he took me in a different way, and again when he asked what I saw I said nothing. A bit frustrated he took me to the services page, and again asked me what I saw. I said strange, but I saw a message that said if someone calls from microsoft saying my machine is sending error alerts, it is a scam. Next sound I heard was click.
