New Windows 10 preview build joins Xbox One in adding MKV file support
Microsoft apparently likes the MKV media file format. A couple of weeks after the company added support for MKV to the Xbox One in its October update, the company has also quietly added support for the format to the new 9860 build of the Windows 10 Technical Preview, which is not available currently for Windows 8.1.
The support isn't quite ready for prime time yet, as you could imagine from an operating system that is still several months from going gold. As reported by Neowin, Windows 10 preview users who try to open a MKV file in Windows Media Player will still get a warning that claims the player does not support that file. However, if they go ahead and try to play the file anyway, they should find that it handles it with no problem. How do you feel about Microsoft adding MKV support in Windows 10 and in the Xbox One?

We need at least update the looks of WMP to make Modern UI looking and maybe some UI changes too. Currently it doesn't blend with Windows 8.X, but I still use it because of alot of features missing on both Xbox Music and Video app.
MKV is just a container. So long as it supported the video codec that it contained, MKV was similar enough to AVI that WMP can play it. I'm pretty sure that you could do this before, and positive that you could do it simply by renaming it to *.avi Here we're getting an error message, that doesn't seem like support at all. it could just be that they're making a best-effort fallback for unrecognized filetypes now.
