    Depends on the exe but it is too complicated & also involving assembly language programming.

    Assuming you want to run something simple like the win 8.1 notepad.exe in win 7, is pretty simple



    Just use CFF explorer and change MinorOperatingSystem, MinorImageVersion and MinorSubsystemVersion from 3 to 1

    Vista is 0, win8 is 2 and so on.

    for NT4 you need to change also the Major vaues from 6 to 4
    Then the exe must be able to run by itself, a too complicate program can't run because other reasons (missing dlls and so on), but the above will surely remove the artificial barriers that MS add to each version jump.
