Windows 11 continues to evolve, and with the release of Build 26200.5670 on the Dev Channel, Microsoft has taken a significant step by introducing the upcoming 25H2 version. This blog covers all the essential details about this latest Insider Preview build, including new features, update methods, changes, and bug fixes.
Let’s explore everything in depth, from the passwordless login improvements to new administrative protections, file explorer bug fixes, and more.
✅ What Is Windows 11 Version 25H2?
Microsoft has officially confirmed that Windows 11 25H2 will be the next annual feature update, expected to roll out in September or October 2025. If you’re using Windows 11 24H2, the update to 25H2 will be quick and seamless—just like a system restart.
🔄 Why Is the Update So Fast?
Here’s how Microsoft is optimizing the update process:
- Shared Servicing Branch: Both 24H2 and 25H2 share the same servicing branch.
- Feature Backporting: Many 25H2 features are already present in 24H2 builds in a disabled state.
- Green Flag Activation: When the time comes, a small update will activate those hidden features, and you’ll be switched to 25H2 without a full reinstallation.
This method ensures that users don’t face long installation times or data disruptions.
🔐 Passwordless Login Gets a Boost
One of the major updates in this build is related to passwordless sign-in options via Passkeys.
How to Access It:
- Go to Settings > Accounts.
- Scroll to Passkeys and then select Advanced Options.
- Before creating passkeys, ensure your Windows Hello PIN is configured.
This is part of Microsoft’s continued push to eliminate traditional passwords in favor of secure, biometric, and device-bound credentials.

🌐 Voice Access and Default Apps Update (EEA Users)
Microsoft has temporarily disabled Japanese voice access support to fix bugs from previous builds.
For users in the European Economic Area (EEA):
- When setting a default browser, it will now automatically pin to the Start Menu and Taskbar, unless you opt out by unchecking the boxes during selection.
This is part of Microsoft’s effort to provide greater app control, especially in line with regional digital laws and user freedom.
🛡️ New Admin Protection in Testing
A new administrator protection security feature is currently being tested. Although it’s not visible to all users yet, it’s aimed at giving admins better control and reducing unauthorized system-level changes.
If you’re a tester or a curious tech enthusiast, you can follow updates and deeper discussions about this feature from trusted sources such as @PhantomOfEarth on X (Twitter).
