windows 11 25h2

Microsoft’s fifth major iteration of Windows 11 is nearing its release to the general public—the Windows Insider team announced today that Windows 11 25H2 was being put into its Release Preview Channel, the final stop for most updates before they become available to everyone. That’s around two months after the first Windows builds with the 25H2 label were released to the other preview channels.

Putting a new yearly Windows update in the Release Preview channel is analogous to the “release to manufacturing” (RTM) phase of years past, back when updates shipped on physical media that needed to be manufactured. Build numbers for this version of Windows start with 26200, rather than 24H2’s 26100.

The 25H2 update doesn’t do a lot in and of itself, other than reset the clock for Microsoft’s security updates (each yearly release gets two years of security patches). Microsoft says that last year’s 24H2 update and this year’s 25H2 update “use a shared servicing branch,” which mostly means that there aren’t big under-the-hood differences between the two. Installing the 25H2 update on a PC may enable some features on your 24H2 PC that had already been installed but had been disabled by default.

Microsoft says that installing the 25H2 update removes PowerShell 2.0 and the Windows Management Instrumentation Command-line tool (both previously deprecated), and that it allows IT administrators to automatically remove some preinstalled Windows apps from the Microsoft Store via Group Policy. But Microsoft hasn’t said much about major, user-facing new features that are unique to the 25H2 update. The 23H2 update from two years ago was a similarly quiet add-on for Windows 11 22H2.

Microsoft released a new Windows Insider build of Windows 11 to its experimental Dev Channel today, with a fairly extensive batch of new features and tweaks. But the most important one for enthusiasts and PC administrators is buried halfway down the list: This build removes a command prompt script called bypassnro, which up until now has been a relatively easy and reliable way to circumvent the otherwise mandatory Microsoft Account sign-in requirement on new Windows 11 PCs and fresh installs of Windows 11 on existing PCs.

Microsoft’s Windows Insider Program lead Amanda Langowski and Principal Product Manager Brandon LeBlanc were clear that this change is considered a feature and not a bug.

“We’re removing the bypassnro.cmd script from the build to enhance security and user experience of Windows 11,” Langowski and LeBlanc write in the post. “This change ensures that all users exit setup with internet connectivity and a Microsoft Account.”

Of course, the removal of bypassnro makes life harder for people who want to exit Windows setup without Internet connectivity or a Microsoft Account. You might be setting up a computer in a place with no Internet connection, or you might simply prefer a local user account like the ones that all past Windows versions allowed you to use.

There are benefits to a Microsoft Account—easy access to any existing Microsoft 365 or OneDrive subscriptions, automated encryption for your local disk and backup of your drive’s encryption key for recovery purposes, and syncing of certain settings between PCs. But using a local account reduces the number of notifications and other upsells that Windows 11 will bother you with. Whatever your reasoning, you’ll need to find a different workaround for future Windows versions.
