In one version, Windows Media Player and Instant Messenger software must be removed; the other version must include links to Web sites that allow consumers to download comparable software offered by competitors. In addition, the company must send CDs to existing users of Windows, allowing them to replace Media Player and Instant Messenger. The FTC also ordered Microsoft to unbundle Windows Media Service from the Windows Server operating system. "The Korea Fair Trade Commission found such tying practices liable because they constitute abuse of a market dominant position and unfair trade practices under monopoly regulations and the Fair Trade Act," Kang Chul-kyu, the commission's chairman, told reporters in Seoul. The FTC decision comes following the conclusion of an investigation into Microsoft's business practices that began in April.
