It works for me on MS Windows also, using an old Emacs 25 build.
Following Alan's recipe gives the behavior he describes:

Perhaps I misunderstood the original bug, but I thought the problem was that when you C-S-right, the text that was highlighted with isearch is no longer highlighted.
Are you saying that that original selection that you were initially on before the C-S-right is still highlighted, or are you saying it isn't, and that's not a bug?
