How to Bypass the Mandatory Microsoft Account Sign‑In in Windows 11 Build 27823

Microsoft recently released a new Windows 11 test build (Build 27823) in the Canary channel, which forces users to sign in with a Microsoft account during installation and has removed the previously built‑in script bypassnro.cmd that could skip this step.

The bypassnro.cmd script originally modified the registry to bypass the login requirement; even though the script is gone, the same effect can be achieved manually by editing the registry, though this is more cumbersome.

Method 1: Use an invalid email address and password to trick the installer. The author repeatedly uses the email [email protected] with any numeric password; the installer shows an error, then allows proceeding to create a local account.

Method 2: Open a command prompt with Shift+F10 during setup and run the shortcut command:

start ms-cxh:localonly

The mnemonic for remembering this command is “启动 微软‑超喜欢:本地only”. The author jokes that using this command makes you look like a hacker to impress others.

Method 3: Use the registry directly. Open a command prompt (Shift+F10) and execute:

reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\OOBE /v BypassNRO /t REG_DWORD /d 1 /f

Alternatively, type regedit to open the Registry Editor and manually set the BypassNRO DWORD value to 1 under the same path.

After applying any of these methods and pressing Enter, the installer presents a window that allows creating a local account without signing in to a Microsoft account.

While a Microsoft account offers conveniences such as syncing settings across installations, users should retain the choice to use a local account, and forcing sign‑in is not advisable.
