Answer 1

I had a main window that I wanted to keep on top of everything (if the user checked "always on top".
This worked for me. Hope this helps someone.

// If we want main to stay on top, we set the rest of the menus to Not be top 
if (mnuViewMainWindowAlwaysOnTopo.IsChecked)
{
    this.Topmost = true;
    
    foreach (var window in Application.Current.Windows)
        // Don't change for main window
        if (window.GetType().Name != this.GetType().Name)
            window.Topmost = false;
}
else this.Topmost = false;
