something along the lines of "Hello, I am calling from Microsoft. I am here to fix your computer. First, go download this software. Then I will fix it."
My parents got this and so did my grandparents. My mom when she heard it said, "My husband is a sys admin so he fixes all the computers in the house.(which is true, i tihnk its a sys admin or something)" Then the guy hung up. My grandpa when he got it said, "I don't have any microsoft computers. all i have are macs." The caller quickly says, "Well, we could probably fix that too." Then the guy hangs up.
Also, have you ever heard of "scam-baiting"? It's a thing where people whenever they get these calls play along with it. And one thing would be to get this call then say, "I'll go turn on my PC" then leave the phone sitting there and come back in 20 minutes or so and see if the person is still waiting.
