The same "trick" will work but becuase the code for that file has likely changed for Windows 7 and been recompiled (or moved to another file) the memory locations listed there won't work.
In fact if you have already made those changes you probably corrupeted one of your system files in some subtle way.
I'd to to the same people that posted that and ask them directly, see if they have updated it for 7.
ANd this is another case of "why bother" because EVERY time that file is updated by windows update or a SP the hack will stop working till you can figure it out again. Hardly seems worth it.
