用hook吧，具体我也不会，但是一定行

Answer 2

1、
procedure TTestForm.BitBtn1Click(Sender: TObject);
var
  Temp: Integer;
begin
  SystemParametersInfo(SPI_ScreenSaverRunning,1,@Temp,0);//屏蔽
end;procedure TTestForm.BitBtn2Click(Sender: TObject);
var
  Temp: Integer;
begin
  SystemParametersInfo(SPI_ScreenSaverRunning,0,@Temp,0);//恢复
end;2、用键盘低层Hook：
function LowLevelKeyboardProc(nCode:integer;WParam:WPARAM;LParam:LPARAM):LRESULT;stdcall;
type
KBDLLHOOKSTRUCT=record
    vkCode:DWORD;
    scanCode:DWORD;
    flags:DWORD;
    time:DWord;
    dwExtraInfo:dword;
end;
var
   fFlag:BOOL;
   p:^KBDLLHOOKSTRUCT;
begin
   result:=0;
   fFlag := false;
   p:=Pointer(LPARAM);
   if (ncode=HC_ACTION) then
   begin
   case wparam of
    WM_KEYDOWN,
    WM_SYSKEYDOWN,
    WM_KEYUP,
    WM_SYSKEYUP:
    fFlag :=(p.vkCode = VK_Lwin) or (p.vkCode = VK_Rwin)or (p.vkCode = VK_apps);
    end;
    end;
    if fFlag = true then
       Result:=1;
    if ncode <> 0 then
       Result := CallNextHookEX(0,ncode,wparam,lparam);
end;procedure TForm1.Button1Click(Sender: TObject);
const
    WH_KEYBOARD_LL=13;
begin
 setwindowshookexw(WH_KEYBOARD_LL,LowlevelKeyboardproc,hinstance,0);
end;
