Hi Bob, Thanks for the input, however, it still does not work. The wallpaper is changed, but I have to press the F5 key to refresh the screen so that I can see the changes :(

Here's my code that I use: uses Windows; const SPI_SETDESKWALLPAPER = 20; begin SystemParametersInfo(SPI_SETDESKWALLPAPER, 0, PChar('c:\WINNT\D2006.bmp'), 0); end. This works for me (also on XP). So perhaps you need to pass a valid .bmp file to update the desktop?
