I got a call at 11:00 PM last night from someone with a strong accent and lots of people talking in the background. I immediately recognized the 'your Windows have been compromised' pitch. So I interrupted his speech and said 'I don't have a computer'. To which he replied, 'someone in your house is using Windows' and I repeated, 'we don't have a computer, you must have the wrong number'. He paused and finally said, 'oh, sorry, goodbye'. Wow, it worked. No screaming, no call back. Amazing they called at 11 and the caller ID said, Las Vegas. Ha. I only answered because my sister is travelling down here from WA and they always stop in Las Vegas. Fooled me.
But Windows isn't going away, they just keep 'improving' it.
