A special thanks to you guys for helping me solve this http://vistastylebuilder.com/forum/index.php?topic=247.0. I am a bit more acknowledged about hacks now.
I have one more little thing to ask to get closer to perfection. How can i get rid of the 1px horizontal separating line shown in the picture, the one that separates the blue bar from the main white section ?

I think it's a part of the command bar image. Search CommandBar in the search box. You'll find it. Change it to see if it's still there.

Check the Explorer & Shell -> Explorer -> CommandModule -> <1> image. It's actually a transparent image overplayed on top of the blue to green gradient. But you can simply use your own fully opaque image

How about the lines in the start menu?  John
