Some OEM machines (for example Dell, MS Surface Pro) that are preloaded with Windows 8.x display a manufacturer logo instead of the Windows generic logo while booting. Even when clean-installed with Windows 10 the logo is still there. I suspect this is stored in the UEFI somewhere, has anyone experience with altering these logos? I would much rather my Windows 10 machines boot displaying the Windows logo than "Dell" or "Surface"
