Bad news for online ad industry insiders with bets that Microsoft will flip-flop on its decision to enable Do Not Track by default: The company is not backing down.

Microsoft’s Chief Privacy Officer Brendon Lynch reaffirmed the company’s commitment yesterday in a blog post. However, he indicated that the upcoming Internet Explorer 10 version will prominently alert users that DNT will be turned on if they select the browser’s Express Settings as opposed to customizing settings. Most users, of course, tend to go with the default rather than personalizing their settings.
