In the latest Windows 11 preview build, Microsoft removed the “bypassnro” command, which let users skip signing into a Microsoft Account when installing Windows.

The command (C:\Windows\System32\) OOBE\bypassnro (.cmd) one types into the command prompt (after opening it with Shift+F10) for the bypass is the location of a batch file they will be removing (the parenthesized parts are optional, implied by the command interpreter, and so is any capitalization). You can still do whatever it's doing (adding a registry key and restarting) by typing the command manually or providing a copy of the file on a USB drive. After a restart, the OS will check for the registry key AND lack of internet connection to provide the local account option.

For the record, the contents of the file are

@echo off
reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\OOBE /v BypassNRO /t REG_DWORD /d 1 /f
shutdown /r /t 0

The first line is optional, and so is the third if you're OK with restarting manually. If creating the file on Unix-based systems, make sure the newline sequence is CRLF (DOS/Windows standard).

Obligatory shoutout to literally any Linux distro, which does not need this workaround, and is usually easier to install and set up than debloating a fresh Windows 11 install.
