Our main goal is to play MKV files in WMP If you want to play MKV using Windows Media Player, you need to install Windows 8 Codecs from Shark007.net. Without it, WMP won’t play this file type.
After it’s downloaded, run it. There’s some extra stuff bundled with the installer, decide whether you need it or not. The rest of the installation is straightforward.
Once installed, it will open a web page and the settings panel for the codec. If you’re running a 64-bit version of Windows 8, be sure to install the x64 components addons after you’ve installed the codec. The link will be in the web page that opens.
Apply the recommended settings.
Now look at the MKV file again. It has a WMP icon, means it will open easily now with WMP. There’s also a thumbnail preview displayed, just like all the other supported video files.
Now you can play any MKV file using Windows Media Player and it will hopefully play just fine.
