Windows Media Player includes some of the most popular codecs, like MP3, Windows Media Audio, and Windows Media Video, but it doesn't include the codecs required for Blu‑ray Discs, FLAC files, or FLV files. If something isn’t working with Windows Media Player, you might not have the right codec on your PC. The easiest way to solve the problem is to go online and search for the codec you need.
You should only install codecs, filters, or plug-ins from trusted, authorized sources, such as the official website of the codec manufacturer. Be careful when you install codecs that you've found on the Internet, particularly the free codec packs that claim to include codecs from many companies, because these codec packs might include software that can damage your PC. If you've installed any codec packs and are having problems with the Player, we recommend that you remove them.
Here are answers to some common questions about codecs.
