Recently made available Windows 10 update KB4046355 for the Fall Creators Update disables Windows Media Player from the operating system. BetaNews reports: While it could be argued that Windows Media Player is no longer an essential addition to Windows -- there are plenty of quality third-party alternatives, such as VLC Media Player, not to mention the Films & TV app in Windows 10 itself -- many users still rely on it. The feature's removal came to light when users installed KB4046355 on devices running Windows 10 version 1709 -- the Fall Creators Update. This update, referred to as FeatureOnDemandMediaPlayer, removes Windows Media Player from the OS, although it doesn't kill access to it entirely. If you want the media player back you can install it via the Add a Feature setting. Open Settings, go to Apps > Apps & Features, and click on Manage optional features.
