how do i change this?

Depends on which operating system you're using. You can use LW's built in player instead. To do that, go to LW's menu bar, Tools>Options>Player & re-enable the player. You may need to restart LW before it takes effect however.

Alternatively, if you wanted to use a different player then change default. See Setting Default video app
