在Windows开始后自动运行一个程序

uses
  Registry;

procedure SetAutoStart(AppName, AppTitle: string; bRegister: Boolean);
const
  RegKey = '\Software\Microsoft\Windows\CurrentVersion\Run';
  // or: RegKey = '\Software\Microsoft\Windows\CurrentVersion\RunOnce';
var
  Registry: TRegistry;
begin
  Registry := TRegistry.Create;
  try
    Registry.RootKey := HKEY_LOCAL_MACHINE;
    if Registry.OpenKey(RegKey, False) then
    begin
      if bRegister = False then
        Registry.DeleteValue(AppTitle)
      else
        Registry.WriteString(AppTitle, AppName);
    end;
  finally
    Registry.Free;
  end;
end;

//例子

procedure TForm1.Button1Click(Sender: TObject);
begin
  SetAutoStart(ParamStr(0), 'Title of your Application', True);
end;
