PC World has neatly summarized all the changes made to Windows Vista due to the European Commission"s demands. The article gives an overview of security-related changes, default search settings, XPS licensing and of course the N versions (no Windows Media Player) succeeding their XP counterparts. Most of it (if not all) has already been covered during Vista"s development, but now that the OS has shipped internationally, it"s interesting to see just how the EU successfully influenced the American software giant: "following discussions with European Commission, Microsoft committed to make a number of changes to the Windows Vista operating system prior to release."
