vu1986 writes, quoting GigaOm: "Microsoft has confessed to violating its browser choice agreement with European antitrust regulators, after they opened up a fresh investigation into the company's behavior. This is a big deal, not least because it means the company could now face a fine of up to 10 percent of its annual turnover — $7 billion at last count." Microsoft agreed in 2009 to inform users they could install other browsers. They did, mostly, but Windows 7SP1 users didn't get the software update. Microsoft is claiming it was just a software bug, and have taken actions to fix it.
