3/18/2013 6:53 pm Pacific time. Received a call from 201-155-2012, Country: USA, Location: New Jersey (Bayonne, Jersey City, Union City . Male caller spoke English with Indian/Pakistani accent. Said he was calling from Microsoft in Washington State because the "root certificate of my computer was about to expire".

I asked him not to call this number, and advised him the number is on the National Do Not Call Registry. I told him I would contact Microsoft during normal business hours and he hung up. Suspect this is a scam to obtain personal information.
