Luna, is the look XP has when it first installs, with the blue taskbar and green start button. The taskbar also comes in silver and olive. This is the Luna Solidasarock is talking about. If your taskbar and start button are grey, and look like Windows 98/2000 did, this is Windows Classic. You can download the Royal theme for Windows XP, install it manually, without the need to patch the uxtheme.dll, I believe this is the similar to the theme that XPize installs. Once the files are in the right place, and assuming you have a working uxtheme.dll, you can change to your new theme in Display Properties. I'm a little new to this myself, but I think what I've said is correct.
