Gates said, "I don't know how I will spend my last day at Microsoft, so I asked some friends to help me prepare for this day. Together, we made a short video, please enjoy it."

Friends who participated in the video include NBC news anchor Brian Williams, Microsoft CEO Steve Ballmer, famous rapper Jay-Z, U2 lead singer Bono, renowned director Steven Spielberg, Hollywood superstar George Clooney, famous TV host Jon Stewart, two leading Democratic candidates Hillary Clinton and Barack Obama, former US Vice President Al Gore, and Hollywood star Matthew McConaughey.
