Thanks for telling me that, TS
And in looking into it some more, I have found alternatives to the native XP skins... Royale Noir and Zune, which can be googled. They are MS certified and can be loaded and used without any modification to Windows XP (aside from placing the Theme files into the respective folder).
That aside, a way that does not require 3rd party software at all is to patch the uxtheme.dll file, which will then allow non MS Certified appearance sets to be used. You can find a large array of styles on DeviantArt, but you still have the windows layout, nothing radical like what I have.
Still, more options without needing to use anything besides "Display Properties" for selection.
EDIT: Zoxxy, is that a Litestep setup? Looks very *unix-ish. Clean, I like it.
