I met serious difficulties in implementing Office on my PC. Support by Microsoft is that I turned, without much hope I confess. And then, surprise! While we were right in the end of year holidays, I received an e-mail every day from the microsoft service staff of new tests and a call on my cell phone to schedule an appointment telephone and finally the telephone appointment about an hour. Also I had only one contact with a real name and a real name. And after the phone call my Office began to walk. Beautiful lesson illustrating what every self-proclaimed "leader" should do. Well done Microsoft.
