ok, found the place where it supposed to be able to change colours and stuff:
right click on desktop and choose Property (or whatever the english word for it is)
go to:
then go to "ERWEITERT" (more or Extra)
then click on "ELEMENT" which should open a list where you can choose a honkeyload of options.
there you have to figure out which one is for the desktop window letters and you can choose fonts and colour and size and.........:
i still havn't found out which one does the letter colour of the desktop but you might try and find out.
