Using HC to mimic classic themes would be the way to do it.
There is once a theme pack released that contained the old themes from Win98 for Win8.
Special Themes (AeroLite and High Contrast variations) - Page 2
And yes they do work in Win10.
From here you can easily build a Win2k theme. For sounds see next post.
The classic or the teal one look pretty much Win2k, with some additional color tweaks, or just like that, are acceptable already.
