A great free Windows 10 theme is the macOS Mojave Dynamic Theme.
You will need to download the UXTHEME patcher for your version of
Windows 10. I am running version-build 1803 and it works great. I also
installed the Classic Start Menu. See my screen shots and a link below
where to find it. The author also created the wallpaper to go with it.
Enjoy...
You can get the theme here:
