MKV is a popular multimedia container to store video and audio files. However, due to its support for a variety of video and audio codecs, the video and audio in MKV can be encoded in different ways, which often causes playback errors on many devices, such as in Windows 7. Since Windows 7 isn’t pre-installed with enough decoders to play MKV files, you may encounter issues like MKV files playing without image or sound or MKV not playing at all. But don’t worry. This article will offer three easy methods to make your MKV files playable on Windows 7. Learn how to play MKV in Windows 7 below.

How to Play an MKV File in Windows 7?

Since the failed MKV playback in Windows 7 is mainly because of the unsupported video and audio codecs, you can use an MKV player, change the codec in MKV, or install the MKV codec for Windows 7 to enable the MKV playback. And here are the three solutions to play MKV files on Windows 7 in detail.

Method 1. Download MKV Player for Windows 7

All you need is to open its "Converter" program where you can add your MKV video. Then click “Play” and enjoy the video. Moreover, it is a powerful MKV converter that can easily convert MKV to Windows 7 supported format for smooth playback (see details in #method 2).
