Windows 8.1 with Toolkit

I am a little Lost ;( 

I have been using the wintoolkit to create great windows 7 operating systems with no problems at all.

So I wanted to start using wintoolkit to start creating cool OS's of windows 8.1.

Doing things like removing the retro crap from 8.1 so it looks and feels like 7.

I downloaded all the latest versions , I think I got 3 versions on my desktop all saying they work with 8.1 

I tried to remove the retro stuff from 8.1

It just didn't work and I ended up getting all mixed up on what did what lol

So I guess I want to know what the correct version is to use to remove the retro desktop of 8.1 ??
