I received a call from an unknown number telling me my MicroSoft Windows registration license was hacked. He provided the name Global Security Department of Windows, 1-866-931-5792, his name Miller and employee number MSW14. He provided a bogus license number and asked me to compare it to the license number on my computer. When I asked him to repeat the license number it was not the same as the first one provided. His supervisor Tony, MSW12 took over quickly when I said I would call back. Tony explained the phone number provided would not be able to connect me to him providing me with the 315-623-4142 number. He explained he was calling from Ontario in the United States.  When I hung up they called me back 3 times asking to stay on the line while I provide the license number from my computer.  Not going to happen.
