Setting:

[a] peHeader.MajorOperatingSystemVersion = 5;
[b] peHeader.MinorOperatingSystemVersion = 1;
[c] peHeader.MajorSubsystemVersion = 5;
[d] peHeader.MinorSubsystemVersion = 1;

would make a binary run under XP, although setting only [a] and [c] should suffice...
Having the source, however, mudlord's is the way to follow.
