As part of its proposed settlement with the U.S. Justice Department, Microsoft has agreed to disclose nearly 400 new items of information describing how Windows works with some of its Microsoft programs, as well as Outlook Express e-mail and its instant messenger programs. Microsoft says it will release the information this month. Some of it will be "free," while payment of a license fee will be required for portions that pertain to data for very large network servers. Still under review by the U.S. Federal District Court Judge Kollar-Kotelly are various U.S. State claims that Microsoft still retains an unfair advantage unless Microsoft's browser is released into the public domain, and that Microsoft's Office software programs must be transferable to and usable on other non-Microsoft operating systems to even the playing field.
