Incorrect quoting. You are invoking:
find . -exec echo c:\cygwin\home\you\{} \;
(or whatever ./{} resolves to), instead of one cygpath per name found by
find.

This indeed quotes things so that cygpath is now invoked once per file,
but at the expense of an additional bash per file as well.
Why not just:
find . -exec cygpath -wa {} +
since cygpath handles more than one file in an invocation (that is,
using '-exec {} +' rather than '-exec {} \;' is generally faster).
