You see, they've re-programmed their entire line to use Bing. It's the default search on IE. In fact, on XP the other day, I did a search for a file from the start bar and that popped up a Bing search. In short, Microsoft has dedicated the most popular operating system in the world to using Bing, and after all that effort, they only have 10% of the market.
Pretty pathetic, I'd say.
