New Windows 11 Build 26120.1330 – New File Explorer and Taskbar Changes, New Settings + Fixes (Dev)

In this article, we will talk about the latest Windows 11 Insider Preview Build for the Dev Channel, which is Build 26120.1330.

There some changes to the Dev Channel:

• this is just an Enablement Package, KB5037898, on top of 26100, not a full new build (26100 is still RTM)
• this will likely head to the Beta Channel at a future date, it comes from the ge_release_svc_betaflt_prod1 branch, packages refer to the Enablement Package as a Beta EKB and it shows up in update history with a title mentioning “Beta Channel”
• the purpose of this EKB and CUs is to test the remaining features for the initial 24H2 release in September as well as features planned to come after GA
• Feature Drops will probably return under a new codename (not Moments anymore).
• For Insiders in the Dev Channel who want to be the first to get features gradually rolled out to you, you can turn ON the toggle (shown in the image below) to get the latest updates as they are available via Settings > Windows Update.

New Features

File Explorer

Microsoft has started rolling out the ability to duplicate a tab by right-clicking on a tab in File Explorer.

Narrator

Microsoft has made several changes to improve the performance of Narrator scan mode. This is expected to make scan mode responses much quicker, especially while using Microsoft Edge, and reading through large documents. To try out scan mode, turn on Narrator first (Win key + Ctrl + Enter), and then turn scan mode ON by pressing Caps Lock + Spacebar during a Narrator session.

Settings

Microsoft is beginning to roll out improvements to Settings > System > Power & battery including the ability to set your Power Mode for both when your PC is plugged in when it’s on battery along with a few other UI improvements to the page.

End Task Button

• Updated the logic for the “End Task” option in the taskbar so that it no longer shows a Not Responding dialog to give confirmation before ending the task.

Other

• Updated System Info (msinfo32) to now follow your text size preference under Settings > Accessibility > Text Size.

Fixes in this Build

Settings

• Fixed an issue where the Windows Update page in Settings was not displaying correctly for Insiders using certain languages (no text showed). If you are impacted by this on Build 26120.1252, updating to this flight should still happen on its own, however you may need to wait a little bit.

Known Issues in this Build

General

• Windows Insiders joining the Dev Channel on PCs running Windows 11, version 24H2 Build 26100.xxxx will see “(repair version)” noted next to the latest Dev Channel build from Windows Update. This is nothing to worry about as all it means is that an in-place upgrade will happen to update your PC to the latest build in the Dev Channel.
• The BitLocker Recovery screen issue documented here may also impact Windows Insiders in the Dev Channel.
• Adding additional languages or optional features may fail with error 0x800f081f.

Windows Sandbox

• Windows Sandbox will fail to launch with error 0x80370106.

Task Manager

• Navigating between different pages in Task Manager may crash Task Manager.
• We’re investigating an issue causing graphs on the Performance page in Task Manager to not show the correct colors when using dark mode again.

Input

• We’re working on the fix for an issue causing text suggestions for the hardware keyboard to not work properly (selecting one unexpectedly concatenates).
