Microsoft delivered in January to PC makers a version of XP minus its Media Player (and 186 other media-related files), as ordered by the European Commission as part of its antitrust remedy. On Wednesday, Microsoft announced it would release on June 15 a revamped version of the product, which has been officially christened Microsoft Windows XP 'N,' to PC makers. No word on what has changed between the two code drops (other than the name). Our guess? Some of those missing media files have been restored. European consumers now will be able to buy retail versions of the product starting in July, according to Microsoft.
