Extract the answer to the question from the following context.
Question: What windows software can play music, photos and videos on PCs?
Context: Music, photos and videos can be played from standard USB mass storage devices, Xbox 360 proprietary storage devices (such as memory cards or Xbox 360 hard drives), and servers or computers with Windows Media Center or Windows XP with Service pack 2 or higher within the local-area network in streaming mode. As the Xbox 360 uses a modified version of the UPnP AV protocol, some alternative UPnP servers such as uShare (part of the GeeXboX project) and MythTV can also stream media to the Xbox 360, allowing for similar functionality from non-Windows servers. This is possible with video files up to HD-resolution and with several codecs (MPEG-2, MPEG-4, WMV) and container formats (WMV, MOV, TS).
Windows Media Center
The context specifies the file types that can be played on Xbox 360 and requires a server or computer with Windows Media Center to stream media. It is well known that only computers using Microsoft's proprietary software, such as Windows Media Center, are compatible with streaming from an Xbox console. As there is no mention of any other software in the passage besides Windows XP (which does not include features for playing music/videos), we can deduce that the answer must be "Windows Media Center.".
