I want to start customizing my Windows XP a bit more, mainly by changing the basic graphics (bar on top where it says program being used, 'Start' button, etc) to create a style. I know it's also possible to create a custom bootscreen and many other things, and was told that this kind of Windows editing (editing skin, not how it works) is legal.
Does anyone know exactly what files you need to edit, how you edit them and how you get them into a usable format, and do more advanced changes like the bootscreen image (usually a flag divided by four with 'Windows' below it)? I don't want to edit much, just replace certain files with custom-made ones (and then have them work properly).
To edit the style, you will need a .msstyles de/recompiler.
To edit the bootlogo, you will need to use ResHack to edit ntoskrnl.exe.
