I have a laptop that was around 6 years old when windows 10 came out (i7 Asus ultrabook). It’s basically incapable of running it, even opening a browser takes over a minute. It runs any linux distro I’ve put on it very well and it’s currently 10 years old, I haven’t had any issues with web browsing, writing documents or anything else. There’s no reason to expect a computer that can browse the web when it rolled off the line shouldn’t be capable of doing so 6 years later. Computers don’t improve that quickly anymore.
The culture of replacing devices every 4-5 years is completely manufactured by device manufacturers and Microsoft. It creates so much unnecessary waste and is destroying the planet.
Removing 3rd party kernel access will probably also make cheating harder. Kernel anticheat is necessary largely in part due to cheat software using exploits in the 3rd party extension system to get kernel privileges itself and evade user mode anticheat.
