What should Bill Gates do if there is a blue screen or a crash when he demonstrates Windows to others?

It was true for a while. When Windows xp first came out. Gates gave a live demonstration. The machine suddenly crashed at that time. Before that, Gates just said that Windows xp will never crash. But it did crash. So Gates said maybe the machine was wet. After the event, a press conference was held to announce that after their investigation, it was really too humid that caused the plane crash. Now you should know that xp will crash, too.
