Windows 11 Insider Preview Build 26200.5670: What’s New?
Microsoft just dropped Windows 11 Insider Preview Build 26200.5670 for Dev Channel users. This update brings exciting features and important fixes. Most notably, it introduces a smooth passwordless login experience thanks to a partnership with 1Password.
Passwordless Login Gets a Boost with 1Password Integration
Now, Windows 11 users can easily set up and use passkeys with 1Password Beta. Just install the app, enable plugin passkey support in Settings, and authenticate with Windows Hello. This means you can sign in to websites quickly using face, fingerprint, or PIN verification.
“You can now use your existing passkeys saved to the plugin credential manager or save new passkeys.” – Windows Insider Blog
Developers building credential managers are encouraged to integrate with Windows 11 to enhance passkey support. This move is a big step toward a safer, password-free future.
Major Updates and Improvements
The build updates the Windows version to 25H2, marking this year’s annual feature update. Microsoft also made tweaks to default browser behavior, now pinning the new default browser to the Taskbar and Start menu by default.
Voice access for Japanese users is temporarily disabled to fix some bugs. Plus, there are several fixes for File Explorer crashes, Start menu glitches, and input issues.
Key Fixes Include:
- File Explorer Home crashing and thumbnail disappearing bugs resolved.
- Duplicate entries in Start menu folders fixed.
- High-impact ctfmon.exe crash affecting typing addressed.
- Memory leak from lock screen slideshow fixed to improve performance.
Known Issues to Watch
Some bugs remain, like touch navigation problems in the new Start menu and Xbox controller Bluetooth crashes. Microsoft is actively working on these, with workarounds provided for affected users.
