Nice work, crskyoem!
Using the files in your package I updated the manual with pages Boot Screen
and Logon Screen
and added step 7
to the Themes page with credits to you of course!
One question: which tool did you use to modify the imageres.dll files? I tried Visual Studio 2008, but after copying all binary image data from the Windows 7 images to the Windows Server 2008 R2 equivalents, Visual Studio didn't allow me to save the file, I expect because of some internal error. I think that is the most clean way to modify the imageres.dll file.
