BURSTMicrosoft has taken a decisive step in its latest Windows 11 Insider Preview Build 26200.5516 by removing the bypassnro.cmd script, effectively closing a loophole that allowed users to install Windows 11 without connecting to the internet or signing in with a Microsoft Account.
This change, announced on March 28, 2025, represents a significant shift in Microsoft’s approach to user onboarding and account management during the installation process.
The bypassnro.cmd script had become a popular workaround for users who preferred to set up Windows with a local account rather than linking their installation to Microsoft’s online services.
The script essentially allowed users to bypass the network requirements during setup, enabling them to complete installation without internet connectivity and without creating or signing in with a Microsoft Account.
According to Microsoft’s official announcement, the removal was implemented “to enhance security and user experience of Windows 11.”
The company explicitly stated that this change “ensures that all users exit setup with internet connectivity and a Microsoft Account,” reinforcing their strategy of connected experiences across the Windows ecosystem.
Windows security researchers noted that this move aligns with Microsoft’s broader efforts to create a more integrated ecosystem where user identities are consistent across devices and services.
Impact of removal
The requirement for Microsoft Accounts enables features like settings synchronization, integrated Microsoft 365 services, and enhanced security measures including two-factor authentication.
The technical implications of this change extend beyond mere user convenience.
The bypassnro.cmd script operated during the Windows setup process, intervening at critical moments to circumvent network requirement checks.
Without this script, users installing Windows 11 will now be required to complete the Microsoft Account sign-in step before proceeding with setup, unless alternative methods emerge from the community.
For enterprise environments, this change raises questions about deployment workflows, particularly for organizations that rely on automated installation methods.
IT administrators typically use deployment tools that create standardized images without requiring individual Microsoft Account authentication, and it remains to be seen how this removal might affect these processes.
This change appears exclusively in the Dev Channel build 26200.5516, which is based on the upcoming Windows 11 version 24H2.
As Microsoft continues to refine Windows 11, this removal signals a stronger enforcement of their connected account strategy ahead of the official release.
