Windows Movie Maker

Windows Movie Maker is a discontinued video editing app developed by Microsoft. It was introduced in Windows Me build 2452, as the beta version of Windows Movie Maker 1.0. The first fully-developed version of Windows Movie Maker was released on 14 September 2000. With Windows XP, version 1.1 was released that brought support for DV AVI videos and WIA-based (Windows Image Acquisition) media importion. Movie Maker 2.0 was released as a free update over Movie Maker 1.1. Windows XP Media Center Edition 2005 brought support for DVD burning.

In Windows Longhorn, an Avalon-based version of Windows Movie Maker was included, however it was later removed due to the development reset. In Windows Vista, the WPF version of Windows Movie Maker was retained and the app gained Xbox 360 playback support, DVR-MS file format support and Direct3D-based transitions. The WIA-based media acquisition was also removed from the app. It's also the first and the last version of Windows Movie Maker that had the same version numbering as most of the other Windows components and apps.

Removal from Windows, reintroduction and discontinuation
Windows Movie Maker would later be removed from Windows and reintroduced in Windows Live Essentials suite as Windows Live Movie Maker. The app went under 3 major updates since then: 2009, 2011 and 2012. The app was also redeigned to use a ribbon toolbar like Office 2007 and Windows 7's Paint.

Windows Movie Maker 2012 is the last version of Windows Live Movie Maker. This version of Movie Maker Vimeo uploading support and MP4 replaced WMV as the default video export format.

The app is discontinued in 2017 and Windows 10's Video Editor (formerly Story Remix, works under the Photos app) took it's place. Some features of the app (such as AutoMovie) made their way into the new Video Editor app. Although if the app's discontinued, you can still run it in the very recent versions of Windows 10.
