diff doesn't work on Windows OS

[AnweshGangula]

I'm using Emacs on Windows and installed vundo today.
I tried using M-x vundo-diff but got an error - 'diff' is not recognized as an internal or external command, operable program or batch file..

The equivilant of diff command in linux seems to be FC as mentioned in this stackoverflow post. So is there a way to configure this in vundo?

vundo-diff doesn't do anything special, just creates two buffers, old and new, and calls diff-no-select on them. So if you can get that command working, it should work fine. Maybe you can install diffutils?
