With regards to privacy and control, yes. There’s loads of telemetry you can’t turn off in Windows anymore, and you can’t even setup Windows 11 without an internet connection.
You can. Today I learned how. You just have to press Shift+F10 to access the console when it asks you to connect to a network and then enter 'OOBE\BYPASSNRO'. That is all.
To skip the security questions set no password initially and then set it later using ctrl+alt+del.
