    I recall seeing WinDiff being used by a Microsoft employee in an 'old' video.  It might have been the VHS tape distributed with NT 3.1 Advanced Server.

    I also think the source for an early version was distributed in a Win32 SDK or Platform SDK.

    IIRC, the windiff source code was distributed with Visual Studio 1.52. Could you put it on github?

    use Beyond Compare, nothing else comes close.
