You cannot get these changes effective immeadiatelybe by
broadcasting WM_WININICHANGE or WM_SETTINGCHANGE messages.
SystemParametersInfo() has no command available for this either.
Solution:
After updating the registry appropriately, SetSysColor() updates the
memory variable that holds the System colors. This method also tells
the screen to redraw. This is esp. needed to update the icons's
background color.
