If true, the news isn't surprising given the European Commission acknowledged back in July 2012 that it had received complaints that Microsoft wasn't providing users with broswer choice. At that point, the EU opened an probe into Microsoft's behavior.
Microsoft offered to make immediate amends, and developed a software fix that would distribute the browser choice screen to PCs running Windows 7 Service Pack 1. The company also hired "experienced outside counsel" to figure out how the omission occured and to prevent it from happening in the future. Microsoft also voluntarily offered to extend the time during which it is obliged to offer the browser-choice screen by 15 additional months.
