In Explorer, select
'Tools'
'Folder Options'
'File Types'
Then run down to where the file types you are interested in are, and you can change them to open with whatever program you like.
IIRC if you delete their entry, next time you try to open them, they will ask you what program to use, select it and click 'remember'.
