Which XP Theme is in use

Hi all,

I want to know if there is a way to detect which theme is in use by XP.

I use bitmaps/icons in my installer and when the Classic or default theme is in use there is a color difference.
I know the icons should be transparent but they are not.


Thx

search the registry for the theme that's currently in use.. then you know which key to query using nsis
