Ever tried connecting your Xbox to Windows OS? Well it connects well and works properly but the only thing that shows up is that its not a Windows Certified Device. A user who connected his Xbox to Windows got to see this: Even without being certified one of the good things about the Xbox one is that it can stream MKV files. MKV is a great format with great compression that doesn’t lose its quality. Reddit user spencep92 was successfully able to play the MKV video file on the Xbox One. With the PlayTo app users can automatically play MKV format files without having to download third party apps. So this is a really good feature the Xbox One offers its users.
