SCAM ALERT call from a suposed Microsoft tech support person I just tell them "I know what your going to say" then he hung up

He called and said "I'm calling about your computer".  I said "which one?"  He then said, "the one running windows."  This is an obvious scam so I asked for his number and name.  Who knows if they were real but it's definitely a scam since he was vaguely talking about a computer.
