Windows Media Center (WMC) is a defunct digital video recorder and media player created by Microsoft. Media Center was first introduced to Windows in 2002 on Windows XP Media Center Edition (MCE). It was included in Home Premium and Ultimate editions of Windows Vista, as well as all editions of Windows 7 except Starter and Home Basic. It was also available on Windows 8 Pro and Windows 8.1 Pro as a paid add-on, before being discontinued in Windows 10, although it can reportedly be unofficially reinstalled using a series of Command Prompt commands.

Media Center can play slideshows, videos and music from local hard drives, optical drives and network locations. Users can stream television programs and films through selected services such as Netflix. Content can be played back on computer monitors or on television sets through the use of devices called Windows Media Center Extenders. It is also possible to watch and pause live TV. Up to six TV tuners on a tuner card are supported simultaneously. Both standard- and high-definition unencrypted video are supported through DVB-T and ATSC standards. It is possible to view encrypted cable television channels by using an internal or external tuner that supported CableCARD.

Shortly after Windows 7's 2009 release, Microsoft disbanded the Media Center development team, thus abandoning any further software developments. Consequently, the Media Center interface remained unchanged for Windows 8 and 8.1 users. In May 2015, Microsoft announced that Windows Media Center would be discontinued on Windows 10, and that it would be removed when upgrading; but stated that those upgrading from a version of Windows that included the Media Center application would receive the paid Windows DVD Player app for free to maintain DVD playback functionality.
