I love vim. I don't know why and I'm not going to try to convince you to love it.
To change vim settings, you need to change the vimrc file. On Linux, this is at: ~/.vimrc. On Windows, this is at: C:\Users\<username>\_vimrc. I also use gvim a lot which is vim with a gui. After all a mouse is pretty useful. Settings for gvim are found in the gvimrc file in the same location as the vimrc file.
