Have had this call 5+ times... today twice and very adamant about him being a legit Windows Tech Support person. He had my CLSID last 12 digits to confirm my Windows license. It was bad. I immediately called my computer tech guy, Bob and decided yes, it was a scam.
Just called my home at 10:48 pm I was busy so I did not answer and they hung up on my machine they have called numerous times throughout the day and extremely late at night I told them to stop calling that I am not going to fall for their scam
Got a call from "Kathleen Bailey" at 9:30pm..sounded like a woman from India in a very noisy crowded room telling me that my computer had a virus..proceeded to tell her that was bs and hung up.
