I have some .mkv files on my system.
Windows 7 does not seem to remember the programs that I used to open those files with.
I keep getting the default open with menu option without any available programs and then select a default program.
Even if open the file with WMP64, Winamp, BSplayer or Media Player Classic, those programs do not appear in the open with context menu, and I cant quickly open the file with those programs.
Is there something wrong which I can fix? thanks in advance!
