Hello, I have been running a total custom theme on Windows 7 for months now, as I am planning my upgrade to 10 I started wondering how I was going to get the custom theme ported. The original maker of the skin has since stopped support (before 8.1). So is there anyway to port the entire theme over to work with Windows 10?

Additional Details:
I have a moderate knowledge of coding and such.
The Themes is very comprehensive including:
Completely Different Icons
New Explorer.exe
New Start Orb
Custom chams (close, minimize, enlarge, back, forward)
