Vista Style Builder

Hey guys. I bought the software but apparently it's too complicated for me. I did get some use out of it with the style hacks and it helped me find some answers to some other questions so I am ok with it.

I have some downloaded themes I use and I used a couple style hacks to spruce up my windows seven theme. What I would like to ask for is can someone create a style hack that squares the corners on browsers and start menu, kind of like this theme but that I can use on my win7 theme. Thanks
