If you wish to disable those key combinations while your application is running call SystemKeys. When you call SystemKeys, if Disable is True, the keys will be disabled, False otherwise.
Note: the code does NOT work under Win NT systems (XP, 2000)
procedure SystemKeys(Disable: Boolean) ;
var OldVal : LongInt;
begin
SystemParametersInfo(SPI_SCREENSAVERRUNNING, Word(Disable), @OldVal, 0) ;
end;
var OldVal : LongInt;
begin
SystemParametersInfo(SPI_SCREENSAVERRUNNING, Word(Disable), @OldVal, 0) ;
end;

Sometimes you want to deactivate the current screensaver when performing some very long process. You can use this function to activate or deactivate the screensaver. Pass True to activate it, or False to deactivate it.
function ActivateScreenSaver(Activate: boolean): boolean;
var IntActive: byte;
begin
if Activate then
IntActive := 1
else
IntActive := 0;
Result := SystemParametersInfo(SPI_SETSCREENSAVEACTIVE, IntActive, nil, 0) ;
end;
var IntActive: byte;
begin
if Activate then
IntActive := 1
else
IntActive := 0;
Result := SystemParametersInfo(SPI_SETSCREENSAVEACTIVE, IntActive, nil, 0) ;
end;
