I have set .js script to open with notepad but I still get other options if I right click.
With files like AVI I do not have the options. I have reset it to open with WMP but stilll should have the option to open it with other players as well.

I have always had the options before - no matter what file type it was - windows would say something like "unknown file type" and would ask me what to do - but does not anymore.
