Windiff for Windows 7


All replies

  • This pack contains it, and should work in either Vista or Windows 7:

    Also made available as a standalone here:

    Note:  Use of the tool under Windows 7 may not be 'officially supported'.  Use at your own discretion, but I've seen numerous reports that it works OK.

  • The version at the softpedia link is 4.0   files dated 1998.. it's over 12 years old and I think it comes from NT4

    gave me a bunch of false positivies when comparing files.   


    I think you'd be a lot better off with a more current version

  • Just a quick recommendation for a very nice commercial comparison tool...   Beyond Compare by Scooter Software.

    Much of the stuff I do as a software developer (and web site maintainer) would be hugely more difficult if I didn't have this powerful tool for giving me quick views about what's different (and what's the same).  It compares blocks of files and individual files with great prowess.

  • Just confirming that should does not means that it will.

    At best it is not reliable at worse does not work at all on Windows 7.

    No matter from where you getting it.

    I don't get it, how Microsoft releasing it own products with such issues? Both are microsoft products at the end.

    WinDiff is one small example of the mess this company developers making.

    Makes me wish to send them to bankruptcy court.

    As a tool to compensate for this incompetence I would recommend small open source tool Notepad++ with powerful add-on called compare. You can get it from and then just select needed options in add-on manager.

  • A version of WinDiff.exe (6.1.7716.0, dated 13May2010) that I have found to operate flawlessy on a 7601 build (AMD64) may be found in the MicrosoftSDKs/Windows/v7.1/Bin folder when you install Windows SDK for Windows 7 and .NET Framework 4 (I use v. 7.1.7600.16385, dated 14May2010), as shown in this screenshot of a folder comparison: WinDiff, Windows SDK 7.1-Compare Folders

    Kudos to JanetFi for pointing this out in this thread:

  • Excellent suggestion. I've got Notepad++ installed and just tried Compare. Solves the problem. Thank you for the suggestion.

  • I've got the SDK installed, as well, and found windiff. Works well also, but I like Compare in Notepad++ better.

  • You are correct Dogtamer. This SDK download has a much later version 6.1.7716. The other posters digress into FILE comparison whereas Windiff does FOLDER comparison. There's even a new version of Orca.msi inter alia!
