tnx, i'll immediatly try the uxtheme dll and will tell you... For the wallpaper, i don't understand how to do...where to begin, on my winxp installed on my pc or in an unattended copy installed in a virtual machine??? EDIT: i received an error with the uxtheme dll..i take your dll, typed makecab and then just copy the dl_ in my i386 folder...so, what's wrong? Must i copy also the uxtheme.dll file with the dl_ one?
