Caller with a heavy Indian accent claimed to be from Microsoft. He said that Windows was receiving error messages from my computer. I figured this was a scam because my computer has been working just fine. I told him I would asked my computer technician to call him back. He said his name was William Smith and that we could reach him 862-405-XXXX (I am not providing the last 4 digits). I did not call him back. FYI, Microsoft does not proactively call Windows users.
