Some of the tweaking on W10 doesn't carry over, such as the tiles/taskbar/start. I talk about that and some other things in the frequently asked questions section near the bottom of the guide. The layout of the guide could use some cleanup and trimming to better address questions like these, and that's something I've been working on the last few weeks (refining all my guides), I just haven't gotten to this big guide yet.
I haven't tried coming up with a W11 attempt at cleaning this stuff up, but even if I were to sit down and do so, it may take weeks or months to configure an elegant, non-hacky solution, the way that I approached W10. This was already difficult enough, and it sounds like it is equally or harder to do on W11...Many people complain about W11's start/taskbar though, so I wouldn't be surprised if tweaks get added by Microsoft in future updates to address it, because the same concept has happened in the past. Here's some W11 resources:
