Windows Live Essentials discontinued. Movie Maker to be bundled with Windows 8
It looks like v15.4.3538.0513 will be the last version of Windows Live Essentials. Movie Maker will now be included as standard with Windows 8.
...the Windows Live Essentials application bundle will go away. Microsoft first announced Windows Live Essentials in 2008, with the first release coming alongside Windows 7. The intent was to decouple the applications—including Mail, Messenger, Movie Maker, and Photo Gallery—from Windows itself, so that they could be regularly updated on their own timetable.
Most of the applications themselves will live on, but in Windows 8 (and Windows Phone) they are pre-installed apps, rather than a separate package. (Source
