Switching OSs will do nothing - MINIX is an operating system with full hardware control operating on ring -3 (the MINIX OS operates on the chip level/its own CPU and you as a user have zero access to it). Operating on ring -3 means MINIX has total and complete access to the entirety of your computer. Even if your computer is “off” but has access to a power source, MINIX can access/change/do whatever with your computers’ settings. Hell it even has its own web server. Just think about what that means - a completely hidden way of communicating online that has 100% access to every single thing on a computer. It’s a privacy/security nightmare.
MINIX is easily the world’s most populous OS and the grand majority of people have zero idea it exists.
Yes. Your OS runs on ring 0. It literally doesn't matter what you have installed as MINIX controls it all and it's pre-kernel. It's the dude (MINIX) playing the dude (your hardware) disguised as another dude (your OS and all other software). To quote Meek Mill, "There's levels to this shit."
I should clarify, when I refer to MINIX I mean that and/or other microcodes interacting at, effectively, the silicon level.
