I want to know the answer to the following question:
Who investigated the bundling of the IE browser with Windows OS?
All the background I'm provided with is that "In January 2009, the European Commission announced it would investigate the bundling of Internet Explorer with Windows operating systems from Microsoft, saying "Microsoft's tying of Internet Explorer to the Windows operating system harms competition between web browsers, undermines product innovation and ultimately reduces consumer choice."". Is that enough to answer the question?
Answer: yes
