How can I use ediff under Windows + NTEmacs?

Question

I have Emacs version 23 on Windows and it seem the ediff executable is missing?

From where can I download ediff for Emacs on Windows?

Answer 1

If you have git for windows installed, then it is enough to add

C:\Program Files\Git\usr\bin\

to your PATH environment variable, because git for windows already ships with a diff executable and installs it in that folder.
