the Acer one I made for my laptop you can make your own easy enough just find a pic or logo you want and use the snipping tool that's in win 7 and win 8 I used my old win7 tool to add logo to my win 8 laptop
Exactly what I had done on my Win7 installation a long while back I have a little matter of a re-installation to do with my Win8, so I'll post my screenshot after that. It's Alienware, LOL!
