REDMOND, Wash.--The random chatter of several hundred Microsoft engineers filled the cavernous executive briefing center recently at the company's sprawling campus outside Seattle.

"It was just silent," said Stephen Toulouse, a program manager in Microsoft's security unit. "You couldn't hear anybody breathe."

hehehe feel pity.
