Microsoft has removed support for most color and font metrics and only keeps themes based on visual styles.
Windows 10 comes without the classic theme engine. Unfortunately, there is no direct way to get the exact appearance of any of the classic themes, especially the ones which have title bar gradients. They have a special place in my heart as a reminder of the good old times of Windows 2000, which was my favorite operating system for many years. Advertisement I always liked how classic themes looked.
