Something i whipped up on my Vista. If you want to change the background to a slideshow of Halo 4 pictures then i'll provide the link to my folder for that (which i use a program to change through as i'm on Vista). Mainly, i made this just to get in the mood for Halo 4. The BG is a Halo 4 picture of the chief, with most sounds being changed to something from Halo (which seemed similar to the original sound in some shape or form).

Really? I have no idea how to get it to work with Windows 8 sorry. you may have to do some research into it. As far as i know, it should work with Windows 7 though.
