This question was solved long ago.
My brother has Windows 7 Ultimate on a Dell PC and asked me to upgrade him (he has no clue how to do things like that) to Windows 10 but then backed out after I told him he would lose his Live Waterfall background wallpapers. He told me if Windows 10 does not have live wallpapers he would never ever upgrade. He uses his computer desktops soothing water fall sounds to sleep, per his doctors orders.
So, how can I enable live wallpapers on Windows 10 Pro? If it does not exist can Microsoft please enable that feature again please? Thank You.
Best Regards
Rod
EDIT: Found the app "Wallpaper Engine" over at my Steam account.
