I was a complete idiot and used this without realising it would remove the start-menu search. (I know there's a warning, I just saw the download link and clicked it without thinking. Very stupid of me.) While Classic Shell works okay as an alternative, I miss certain features of the original Windows Search. I'd be incredibly grateful if someone could help me re-install Cortana (and the Windows Search).
Many thanks in advance.
(This didn't work.)
