    Exclamation Windows Media Player does not open wmv files

    Windows Media Player found a trouble as I click to open .wmv files.
    I thought it had already come with the codec for .wmv.
    MEdia Player does not open .wmv files.
    I noticed on WIndows XP SP3 the same problem as I try to open .avi files.
    Where to download the codec for wmv from ?

    .wmv is the most standard file and should open. Maybe you have some corrupted system file. Run SFC /SCANNOW in an elevated cmd. Maybe it can fix it. No need to download any codec. Your .avi story is different.

    Create a system restore point first.
    Download wmv fix for Windows 7 from winhelponline and apply it.
    Should help.

    Default player

    Hello Ron Wolpa. Have you tried to reinstall Media player ?

    Sounds like some conflict between media player and any other player on your machine.
    Have you installed anything since the last time it worked.
    Try to remember and then uninstall it, and see if it works then ?
