Windows Media Player 11(June 3, 2005)
Microsoft changed his plans for the new version of WMP 11, formerly known under code-name 'Aurora'. That version wouldn't have many new features, but that's changed. The WMP Longhorn version will also come for XP, this will be WMP 11.
There's just one problem: Instead of shipping in November, as per the original plan, WMP 11 will now ship in a public beta during that month, coinciding with Longhorn Beta 2. The final release is roughly scheduled for early 2006.
