Comment 4 for bug 1422248

Because doing so in Win 7 causes windows to change the user specified default programs,
at least that was what I read somewhere. Maybe that is not true, but I
will leave it win8 for now, if it works well there, I can test it on
win7 later. Besides the win 8 default programs UI is much worse that win
7, many people dont realize they can simply browse to and choose an exe,
so there is more need for it in win8
