For .Net 3.5 SP1 you can use:

public partial class MyWindow : Window
{
    public MyWindow()
        : base()
    {
        InitializeComponent();
    }

    protected override void OnSourceInitialized(EventArgs e)
    {
        var hwndSource = PresentationSource.FromVisual(this) as HwndSource;

        if (hwndSource != null)
            hwndSource.CompositionTarget.RenderMode = RenderMode.SoftwareOnly;

        base.OnSourceInitialized(e);
    }
}

And also you can set it through the register

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Avalon.Graphics\DisableHWAcceleration
