I love Google, but this is just pathetic:

Google has informally complained to U.S. and European antitrust regulators about what it says are biased settings on Microsoft’s latest Web browser, marking the latest spat between two companies whose business models are increasingly bumping up against one another.

Google’s charge, isn’t true, as you can see in my screenshot.  My IE7 is set to Google by default becuase IE6 was, and even if it wasn’t, the change is very easy to make.

However, even if it were true, it’s fully within Microsoft’s right, and in fact might be expected by their shareholders to favor their own search engine over Google.  By complaining to a regulatory agency, Google is basically claiming that Microsoft doesn’t have a right to pitch its own products before others.  And this is coming from the dominant search engine on the market!
Meanwhile, the Firefox browser is set to Google’s browser by default, and does not even have MSN Search as an option. In exchange the Mozilla corporation makes millions from Google searches.  MSN search is also notably absent from Google Desktop and other Google applications.
