Five years ago all I knew was that Windoze was cancer, so I just built a new box and installed Linux on it. It just werked. I never went back, and won't. It's not even hard. The malevolent company I provided so much data to over many years is out of my life, and that was what I wanted. I am utterly confident that you have the necessary ability to do the same, and your life may depend on it, given the atrocious privacy laws in E. Asia.
