Windows Media Player

Windows Media Player, or Media Player, refers to a family of multimedia player and library applications developed by Microsoft and normally included with Microsoft Windows. Depending on the Windows version, there might be multiple distinct versions of the application, all using a similar name but including different features.

A multimedia player, then called Media Player, was originally introduced as a part of Windows 3.0 with Multimedia Extensions 1.0, where it was implemented using the Media Control Interface. A slightly updated version of the player then shipped with Windows 3.1. A larger update was included with the Video for Windows suite; this version of the player would be then ported to 32-bit Windows and included with Windows NT 3.1, Windows 95 and later, all the way until Windows Server 2003.

In 1998, Microsoft first released the Windows Media Player, a new player which unrelated to the MME player. The first edition, often called the "classic" Windows Media Player, had a fairly short lifetime, as it was only officially bundled with Windows 98 Second Edition and Windows 2000 as version 6.1 and 6.4, respectively. However, it continued to be bundled with newer player versions, albeit hidden. Version 7.0, released in 2000 along with Windows Me, was partially based on scrapped Music Center work done for Windows Neptune and introduced a brand new interface. Later versions up to and including 12 introduced additional UI changes and feature additions. Microsoft ceased active development of Windows Media Player after Windows 7 shipped in 2009, making Windows Media Player 12 the final version of Windows Media Player.

The player is still included in Windows 8 and later, but its functionality has been superseded by the new Microsoft Movies & TV and Groove Music applications. The name Media Player was revived in Windows 11 as Microsoft redesigned the Groove Music app to also support video playback. The new version was first introduced in November 2021 and was then publicly released to all users in February 2022. In order to distinguish it from the modern Media Player application, the older player is renamed to Windows Media Player Legacy since Windows 11 2022 Update.

History
The first version of Windows to include a media player is Windows 3.0 with Multimedia Extensions 1.0. Slightly updated versions of the player then shipped with Windows 3.1 and later revisions of the 16-bit Windows environment. The player is implemented using the Media Control Interface, an extendable API introduced with the Multimedia Extensions. By default, MCI only supports playback of wave audio and MIDI files as well as CD Audio, although support for other formats and devices can be added by installing additional so-called MCI drivers. Although Windows 3.1 and later don't include MCI drivers for any video format, the player is still capable of video playback if one is added post-install, displaying the video content in a separate window.

A larger update, internally called "Media Player 2", was introduced as a part of the Video for Windows suite with an updated user interface and support for copying media to documents via OLE. The suite also includes an MCI driver for the new AVI format. This version was later ported to 32 bits with some minor changes and included with Windows NT 3.1, Windows 95 and later. It would continue to be bundled with Windows even after the newer versions were introduced, with the last version of Windows to include it being Windows Server 2003.

Except for the versions bundled with the Multimedia Extensions and Video for Windows, this original incarnation of the player didn't adopt its own versioning scheme and instead used the Windows version number.

Windows Media Player 5 and 6
In 1996, Microsoft introduced the NetShow multimedia framework for network broadcasting and along with it developed the new NetShow Player to support the platform's then-new ASF container format. The first two versions of the player were rather rudimentary and only supported ASF format playback. At the same time, ActiveMovie, the successor to Video for Windows that also added support for MPEG playback, was also introduced, together with its own player called ActiveMovie Control.

Two years later, ActiveMovie was renamed to DirectShow and incorporated into the DirectX suite. Work also started on a new version of the NetShow Player with a new user interface that would also adopt DirectShow for media playback. However, as the company relaunched NetShow as Windows Media and aligned its version with DirectX, the player was rebranded and NetShow Player 3.0 ultimately shipped as Windows Media Player 5.2. Multiple updates were then released to the player in the following months, eventually bringing it up to version 6.4.

This edition was only officially bundled with Windows 98 Second Edition and Windows 2000 in version 6.1 and 6.4 respectively, although it is also included together with newer player versions in Windows Me, Windows XP and Windows Server 2003, albeit hidden. After the introduction of the new user interface in later versions, it started to be often unofficially called the "classic" Windows Media Player. However, newer Windows Media Player versions up to version 9 still include a Classic skin, which closely replicates the older user experience. Several open source projects, namely Media Player Classic and its forks, also aim to clone the user experience of Windows Media Player 6.4 while also adding features found in newer multimedia players.
