Windows 11 Insider Preview Build 26120.4520 Hits Beta Channel

Microsoft just dropped the latest Windows 11 Insider Preview Build 26120.4520 for Beta Channel users. This update targets version 24H2 and brings some cool new features and important fixes. If you’re part of the Insider Program, it’s time to check out what’s fresh and what’s improved.

What’s New: Passwordless Login Gets a Boost

One standout update is the new plugin passkey integration with 1Password. Microsoft teamed up with 1Password to simplify passwordless sign-ins on Windows 1 Setting it up is a breeze: install 1Password Beta, enable the plugin in Settings under Passkeys, and verify with Windows Hello (face, fingerprint, or PIN).

Now, you can use existing passkeys saved in 1Password or create new ones directly from supported websites. The process is seamless, letting you sign in quickly and securely.

“You can now use your existing passkeys saved to the plugin credential manager or save new passkeys.”

This integration means your passkeys sync smoothly across devices, enhancing security without sacrificing convenience. Developers are also encouraged to integrate their credential managers with Windows 11 to support this feature.

Major Fixes and Improvements

Microsoft tackled several bugs that were affecting daily usability. File Explorer crashes, especially on the Home page, have been fixed. Thumbnails for pinned favorites now reliably show up again.

The Start menu got some polish too. Duplicate entries when opening folders are gone, and folder expand animations are smoother. A pesky ctfmon.exe crash affecting typing has also been resolved.

Additionally, memory leaks caused by slideshow lock screen settings have been patched, improving overall system stability.

Other Notable Tweaks

Default browser changes now pin the new browser to Taskbar and Start menu by default.
Dialogs better support increased text scaling for accessibility.
Japanese voice access support is temporarily paused to fix bugs.

Known Issues to Watch

Some bugs remain. Touch gestures on the new Start menu aren’t fully reliable, and drag-and-drop from “All” to “Pinned” is limited. Xbox controller Bluetooth users may face PC crashes, but there’s a workaround via Device Manager.

Windows Update may throw error 0x80070005 for some, with a suggested fix through Recovery settings.

“Using touch to navigate the new Start menu may not work reliably.”

Final Thoughts

This build is a solid step forward for Windows 11 Beta insiders. The 1Password passkey integration is a game-changer for passwordless security enthusiasts. Meanwhile, the bug fixes improve everyday reliability.

Keep the toggle on in Windows Update to get these features as they roll out gradually. Insider builds are experimental, so expect some rough edges but also exciting innovations.
