That’s basically what it was for me. For many years I’ve had a folder saved on my computer called “registry tweaks”, in which I’ve maintained a growing list of notes about all the settings and registry edits and other cruft I have to change to make Window less-shit. (Most of it is about the registry, but not all.)

That list of tweaks just kept getting longer; but there was also a growing set of things that were bad and unfixable; (various nags, and surveillance / telemetry etc.) . No one thing was intolerable, but as a whole - it just isn’t worth it any more. It’s easier to learn to use an entirely new OS than to continue to wrestle with the enshitification of Windows.
