Windows is a good and stable OS with a reasonable privacy, BUT ONLY if the first thing you do in a new PC with Windows, to spend an afternoon disabling and throwing out a ton of junk, trials, unnecessary services and functions and most of the telemetry. So if you have a fast and compliant OS. Luckily Windows allows all this, but naturally it requires an advanced user (registry and servicelists can be a comanche territory if you don’t exacly know what you do) and M$ does not offer much documentation and help on this topic either, of course. But in the new online subscription version they will naturally nip these possibilities in the bud.
