I was using OpenShell with W10 so needing a thirdparty taskbar isn't horrible. I see people complaining they can't truly disable updates on 10, which I did without too much of an issue. Truly removing and shrinking down everything was a project, but it's been solid and fast since doing so.
I kept a lot of notes and a lot should still apply to 11, but it's still a chore. I'm actually looking at recreating Tiny11 as a base and figuring out what to manually add back on a case by case basis to have all the functionality I need.
I will need something to run GTA6 when it comes, if nothing else.
The task/start bar is unfortunately not size adjustable anymore and requires third party replacement if you want that back.
It can be molded back into a reasonable Windows experience, but I imagine future updates will break every change I make at least once.
