I can't figure out my video problem
 

I have a kodak picture viewer on my pc, and now all videos I try to download are using it to look at. How do I switch all my downloaded movies back to windows media.

You need to select one of those files in question & make WMP the default again. I think you might be able to do that within WMP (unless I'm mistaking it with another program.) But the ideal way to do it is following samples here: Setting Default video app Use same principle.

I feel like an idiot, and still confused
 

I have no idea where I can manipulate the files. They were once win media, for some reason they changed to the kodak program. I would like to change it back to win. media. everywhere I try to change it, inside the propertys button it only has "play", not "play with"

please help

try to reinstall windows media player that word for me
