In this article, we will talk about the latest Windows 11 Insider Preview Build for the Dev Channel, which is the Build 26200.5670.
Windows 11 25H2
With this build today, Windows Insiders in the Dev Channel will see the versioning updated under Settings > System > About (and winver) to version 25H2. This denotes that Windows 11, version 25H2 will be this year’s annual feature update. As mentioned here, Windows 11 will have an annual feature update cadence that releases in the second half of the calendar year. For more information, see this blog post here.
New Passwordless Improvements
Microsoft have partnered with 1Password to bring users a seamless plugin passkey provider integration in Windows 11. Setup is simple and intuitive:
- Install 1Password Beta on your Windows 11 PC.
- Go to Settings > Passkeys > Advanced options to enable the plugin credential manager.
- Toggle on support and complete user verification with Windows Hello (face, fingerprint, or PIN).
- You can now use your existing passkeys saved to the plugin credential manager or save new passkeys.

To use a passkey, go to a website where you have an account with a passkey you’ve saved to your credential manager and select that passkey. Sign in quickly and easily with Windows Hello.

Save new passkeys to your credential manager by going to a website that supports passkeys. Find the option to create a passkey for your account, choose to save to your credential manager, authenticate with Windows Hello, and your passkey is saved.

Voice Access
Microsoft is temporarily disabling support for Japanese to iron out a few more bugs.
New Settings
In addition to the small changes that we made in the EEA region for default browsers via Settings > Apps > Default apps with Build 26200.5603, we’re also making this change:
- The new default browser will be pinned to the Taskbar and Start menu unless you choose not to pin it by clearing the checkboxes.

Fixes in this Build
File Explorer
- Fixed an issue which could cause File Explorer Home to crash (potentially also making File Explorer crash on launch, since Home is the default section for File Explorer).
- Fixed an issue which could cause the thumbnail for a pinned favorite in Home to disappear.
- Fixed the issue causing File Explorer to not persist view changes after the last Dev Channel flight, including desktop icons.
Start Menu
- Fixed an issue which was causing duplicate entries to appear when interacting with folders on the Start menu.
- Fixed an issue where the folder expand animation wasn’t correct in some cases.
Input
- Fixed a high hitting ctfmon.exe crash in the latest flights, which could impact the ability to type.
Other
- Fixed a memory leak which could happen when lock screen was set to use a slide show, which could impact performance and reliability over time.
- Did some more work improving how dialogs in the system react to increased text scaling, for example the “You must restart your computer to apply these changes” dialog should now support it.
- Fixed the issue causing the Windows Vista boot sound to play instead of the Windows 11 boot sound. Unfortunately the fix wasn’t completely working in the last Dev Channel flight.
