I've been studying this also. Microsoft, it seems, doesn't want Windows users to have real choice so they have created blocks to adding search providers; probably in a recent security update. In some web searches I did find someone that had written a registry script that added all the necessary keys to manually add google to the search providers in IE11. No doubt someone skilled at registry keys could do this for DDG?
