In the past our desk.cpl ran perfectly fine in Windows XP SP3.
Since some recent shim / apiset refactoring, it does not longer run, because it now depends on advapi32_Vista.dll
I tested desk.cpl from 0.4.11-dev-890-g3050d93 gcc dbg build.
The app does not start at all anymore and also presents no messagebox.
Please allow it to run again.
