mount install.wim, go to mount location\windows\system32\imageres.dll open with restuner or reshacker open folder image I changed all of these images to the one I wanted. I just saved them as different sizes as needed. Use photoshop or gimp or whatever to edit your images. Also, not sure if it's necessary, but I named my edited images the same as the originals, 5031.bmp, 5032.bmp, and so on. edit: images are .jpg not .bmp
