    Adding (Not Changing) An Extension in Win8.1

    I'd like to add a file extension to the list given in Control Panel/Default Programs. In WinXP the process was simple, However, in Win8,1 I can not find a way to do it.

    Windows 8 is more difficult & complex for a reason: security...
    and more of a pain in the butt too for: Metro/start screen apps taking over desktop associations.

    Have a look at the above links.
    It would be a good start to first disassociate, some or many, of the Metro type apps from vying for dominance.
    Invest a little time and energy in a well thought out BACKUP regimen and you will have minimal down time, and headache.
