不好意思代码有点问题,需要修改一下.
procedure TForm1.Button1Click(Sender: TObject);
var Res:TRegistry;
begin
   Res:=TRegistry.Create;
   Res.RootKey :=HKEY_USERS;
   If Res.OpenKey('\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer',False) then
   begin
      Res.CreateKey('\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer');
   end;
   Res.WriteString('NoLogOff',IntToStr(1));
   Res.Free;
end;
