Madeline, I also received a call from this number (reading "Detroit Lake, MN" on caller ID) but did not pick it up.  In the past I  have received the "Microsoft Support" obviously phony phone call from other phone numbers, and did a little research on it.  This is a scam to scare you and urge you to allow them to gain access to your computer, so they can create problems on it that they want to charge $ (i.e., a ransom) before they fix it.  So understand that this bad language fellow was not trying to make a legitimate sale, and he will not lose his job because he is not operating on behalf of a legitimate business.  These are the worst of the worst.

Most of these calls are coming from India and Pakistan.

At least this one was worth a laugh. After I said hello and there was a pause, some obviously Indian or [***] guy with a thick accent said, "Hello, this is Peter Williams from the Microsoft Windows Center and..." I interrupted and said, "LOL, your name is not Peter Williams, what is it really?" and he hung up. Who ARE these clowns?

Yeah, I had the same thing. I told him my name was Steve Wozniack and my phone was hooked up to my computer and I was about to test my new invention on him by pressing a key and sending a lightning bolt through the airwaves to come out of his phone and punch him in the head. He hung up

Interesting.  I live north of Toronto and got the call today.  The accent was really thick , but I think thats the name he tried to use.  I told him that with an accent as bad as his he could only be with the Canadian government. No way he could be private sector.  Too funny, oddly he hung up.
