Excellent thread.
I have a question about nLite - in the options section, on the patches pane, there is the option to enable unsigned themes support via the uxtheme.dll patch. I was under the impression that the initial batch of patched uxtheme.dll files would not work with the final version of service pack 2. I know there are later ones which work with SP2, but I don't know if they are backwards compatible so that's why I'm asking this question:
Am I able to use the unsigned themes support in conjunction with a slipstreamed SP2?
