This is the first version of gsw953onDA @ deviantART Gray theme for Windows 10. There will also be version 2. Shortly after he finishes the work for it (improvements, colors, scheme etc.)
If you are a dark theme fan, this is a perfect choice!
What he says about it:
“I really love it and I enjoy coding and developing on it. It really rests my eyes. Let’s take a preview and then you can download it and install it for free.”
