Like you, I've received dozens of calls saying the caller is from "Windows" and my network is malfunctioning.
Now, there's a new twist. I just received a recorded message saying it was "emergency call" from Microsoft because my licenses had expired and all Microsoft products were going to be shut down immediately. To prevent this, a phone number was given to call to prevent the disaster.
Ha. I slammed down the phone, not just because I have Apple computers, but because know the scam method. It's so annoying. I wish federal and state agencies could keep with these scammers and shut them down.
My advice is for consumers to hang up as quickly as they can. No need to be polite to these fraudsters.
