You need to call the GDI DeleteObject method on the IntPtr pointer returned from GetHBitmap(). The IntPtr returned from the method is a pointer to the copy of the object in memory. This must be manually freed using the following code:

[System.Runtime.InteropServices.DllImport("gdi32.dll")]
public static extern bool DeleteObject(IntPtr hObject);

private static BitmapSource LoadImage(string path)
{

    BitmapSource source;
    using (var bmp = new Bitmap(path))
    {

        IntPtr hbmp = bmp.GetHbitmap();
        source = Imaging.CreateBitmapSourceFromHBitmap(
            hbmp,
            IntPtr.Zero,
            Int32Rect.Empty,
            BitmapSizeOptions.FromEmptyOptions());

        DeleteObject(hbmp);

    }

    return source;
}
