I don't want to use Prism or MVVM Light solutions and would like to pass two parameters to the second window? How could I do that? I was looking for some information on this topic, but unfortunately most of them use packages...

try this:
App.xaml
<Application.Resources>
<vm:MainViewModel x:Key="YourViewModel" />
</Application.Resources>
MainWindow.xaml

I guess you could just send parameters in the constructor of the second window, wherever you are creating your window.
var newwin = new SecondWindow("second param is int", 42 );
newwin.Show();
And then just create an another constructor for your window:
public SecondWindow(string a, int b) : this()
{
var secondVM = (SecondViewModel)DataContext;
secondVM.IAmSendingYouTwoParams( a,b);
...
}
