This tool lets you play all kinds of multimedia files, both videos, and audios, having support for an endless number of formats and encoders. You can associate it with the most common file extensions and use it as your default player. You can also use this version of XP to extract audio tracks from a CD (in WMA format with or without protection), burn music and video CDs or tune in to online radio and TV stations.
Windows Media Player is also capable of working with subtitles, synchronizing audio, making changes to the video aspect ratio in real-time or creating playlists among many other features. Its only drawback is that it is not as light as other alternatives, but it makes up for that fact with its robustness and obvious integration with the rest of the operating system as it is an official Microsoft product.
