Add a file type to default programs in control panel
Win7 control panel offers a similar 'open file type with' dialog that is in XP.
However I've noticed that there is a problem with the extension MPEG4, MPEG-4. MPEG-4 filetype
does not appear on the list. There are options to 'change" but no "add" that I can see.
How can an additional file type be added? As is, I cannot select the proper program to open.
