Of course, who can forget the most infamous BSOD of all time, which perfectly summed up the state of the Windows operating system at the time. When in 1998, in front of hundreds of people watching live, and millions subsequently later, a Microsoft employee plugged in a scanner live on stage while Bill Gates was smiling through his Windows 98 presentation, the system crashed with a magnificent BSOD on the screen. The audience erupted, prompting Gates to say, "That must be why we're not shipping Windows 98 yet." I'm sure deep down, Gates was mortified for half a second, just like every Windows user who ever saw that blue screen for the very first time.
