Now that I've successfully modified the Windows 2000 splash screen, I want to try the same thing on Windows XP. Remember how XP RTM and SP1 had the "Professional" designation on the splash screen? I do, and I want that in SP3. So, first thing I did was to set up a fresh copy of XP Professional RTM and I looked to compare its NTOSKRNL.EXE with that of a fully updated XP Professional SP3 install. Problem was: The bitmap resources in NTOSKRNL.EXE seem to be mostly blank, and mostly the same between the two. Are the actual bitmaps used for the splash screen stored elsewhere? What am I missing?
