Received a recorded message from 800-604-3962 on 8-18-17, informing me that my Microsoft product key had expired. Call 800-569-1481
for details. Knowing that product keys do not expire, I did not return call knowing that it is some sort of scam. I was tired but normally in my good humor, I would call them back to play with them and tell them that I don't have Microsoft products, but that I use Apple. That stops them! But now I have received calls about my Apple computer! I think they all talk to each other, who ever they are. Fun.
