Yes, you can play any type of media file (MP3, Quicktime, MPEG4, Real) with “Windows Media Player“. All you need is a CODEC. The “K-Lite Mega Codec Pack ” installs pretty much all of the known CODECs, even the one’s that most of us are not familiar.
Sometimes a file will not open but if you save it to your desktop and then open it should work. (You may have to choose WMP to open it.) If it isn’t in this CODEC pack (CAUTION) do not download one from the site that is suggesting it. It may be malware.
This does not include server-side applications like “Flash” and “Silverlight”
Note: Do not install “Media Player Classic” that is included in CODEC Pack. If you do it will be the default player and you want WMP.
