South Korea's largest Internet portal, Daum Communications, is seeking a court injunction to block the sale of Microsoft's Windows XP operating system in Korea.
The latest version of Microsoft's flagship product is scheduled for widespread retail release on October 25th.
The company filed a complaint against the sale of Windows XP with the Seoul District Court Thursday. In the complaint, Daum said Microsoft's bundling of a variety of application software, including instant messaging, with Windows XP constitutes an unfair business practice.
The complaint also accused MS of infringing upon users' privacy by demanding excessive user information when installing Windows XP in the computers.
Daum said it will take collective action with other companies to counter the sale of Windows XP.
The initiative follows a similar complaint filed in early September by Daum with the Korea Fair Trade Commission over the bundling issue. The commission has not acted on the matter.
Microsoft said it will not act until the court or the F-T-C issues a ruling.
