So, ive got a 13900k system now, and I just cant bring myself to use windows 11.
This is interesting.
As for the start bar on 11 that is what Start11 is for. It takes care of the start bar but your still stuck with the new explorer. There is a hack to getting the explorer back but I had issues with it. It worked for a while then I had to change the shell back. I believe the issue was because it was unsigned.
