"Microsoft Windows" scam. I kept asking how they got my number and the guy kept trying to pretend he was some sort of tech support. It was pretty hilarious.

Called my mom trying to ask about our windows computers  and claiming they work for "Microsoft Windows". She handed me the phone and I asked why he was calling. Asked if we had windows computers in the house. I explained that we only have macs and asked repeatedly why he was calling and how he got our number.

Eventually hung up on me. Sounded like a total scam and I hope no one falls for it.

I don't answer the phone no more. Too many scammers.
In the case of this number, the caller did not leave a message on the answer machine. Calling at 7:15pm

With an foreign accent "Calling about your computer."
