You need to change the system Path, not the user Path.

Alternatively, rename the MS find.exe to something else.

No, don't do that, it won't work (as you have found out).  Emacs
sometimes invokes commands through the shell, which doesn't know about
exec-path.  This way lies madness.  You should have your PATH and the
corresponding Emacs variables in sync.

(This is all basic Windows setup, nothing related to Emacs, btw.)
