The developer who put that in needs a raise.

I’ve also heard that the following trick still works: enter the email address no@thankyou.com with any password, this account has been tried so many times that it’s been locked out, so the installer will let you continue with a local account

Afaik this doesn't work anymore on Windows 11 unless you change some configuration in the shell and reboot before doing the setup.

Windows 11 Home requires you to get a working internet connection to continue. Windows 11 Pro doesn't as of the 22H2 version but it still has dark patterns. For Office you can still use other licensing methods, even for O365, but as a typical consumer getting it legitimately you'll de facto need a Microsoft account.

Using "no@thankyou.com" for your Microsoft account (and any made up value for the password) allows you to skip this requirement in any version of 10/11 as someone got that account banned and the Microsoft workflow bails out since they naturally don't want to force onboard a banned user to a new account. This still requires internet during install though, it just works around needing to make an actual account.

It's a shame how much of a dance the install process has become.
