As far as I know, all the patched versions of uxtheme.dll created before the final release of XP SP2 do not work with it. However, I do not know if the new versions that do work with SP2 final are backwards-compatible. What I'm asking is: Does the patch for unsigned themes support in the options > patches section of nLite 1.3 RC2 work with XP SP2 final? Thanks.
