This is working fine in Win95,98,ME but in XP or Win2000 this function CANNOT disable these keys. The question is how can I disable the fast switch keys IN XP(Win2000)?

The Platform SDK specifically states, "SPI_SCREENSAVERRUNNING Windows 95: Used internally; applications should not use this flag. Windows NT: Not supported."
