Update 19 Dec 2012:
New Windows 8 logo! Are you tired of your laptop manufacturer logo and you want to make your laptop unique? My acer laptop has its logo illuminated whenever the computer is turned on, even if the display is turned off. So I thought the new Windows 8 logo might be a good match to cover those.
What you need is just plain Windows 8 logo image file. Print those using the windows built-in print function, and select contact sheet as the size. Now cut your sticker according to that printout and you're done.
