Okay, I have been struggling with this all night and I've finally decided I am going to need to ask for help on this

I'm Andrew by the way.
Okay let me start off with what I am running:
Windows Vista Home Premium
The Fleur-De-Lys theme
I would like to compact the start menu so that the right panel is non-existant, or so that it only shows maybe 10px of it. I have already edited some registry files to remove the shut down and log off buttons etc and this side is now completely empty, bar the small arrow that did used to be the menu for the shutdown options.
So what I have right now is:

And what I want it like is this:

Basically I am doing everything that has been stated above, ie editing the 1033 file, and editing the hex etc. But when I go to apply the visual style in the control panel it says "Cannot load visual style" and one time when I tried it it said run32.dll had to close and closed the theme chooser.
Has this happened to anybody esle?
Is it possible to do what I am asking?
Any help would be greatly appreciated, thank you
Apologies if I should have posted this elsewhere but I was following these instructions so I figured it was on topic.
