What changes

Improvements 4 changes

Certificate renewal for Windows Insiders

For: Windows Insiders

  • The build includes a renewed flight certificate so Insider devices can remain on supported builds and continue receiving future Insider Preview updates. The current certificate expires on August 11, 2026.1

Settings

For: Insiders in the Beta Channel

  • You can navigate the Bluetooth quick settings page with a gamepad.2

Search

2 items

For: Insiders in the Beta Channel

  • Search makes it clearer whether a result is an app, setting, file, web result, or Store suggestion.4

Fixes 3 changes

Windows Update

For: Some Insiders in the Beta Channel

  • Some Beta Channel Insiders no longer experience installation rollbacks with error code 0xc1900101 when installing the latest builds.5

Storage

For: Insiders who back up to network shares

  • File History automatic backups to network shares work again instead of failing with an invalid credentials error.6
    Fixes automatic backups to network shares using Server Message Block (SMB).

File Explorer

For: Insiders using a DFS mapped drive

  • Files on a mapped drive are no longer incorrectly treated as coming from the internet after the device starts without a network connection and reconnects later. This also prevents the Preview pane warning that a file could harm your computer.7
    Addresses incorrect internet-origin classification for files on a Distributed File System (DFS) mapped drive, which could also add an unexpected Mark of the Web to copied files.

New features 3 changes

Taskbar — Alternate Taskbar Position

For: Insiders in the Beta Channel

  • You can move the taskbar to the bottom, top, left, or right of the screen. Some features are not yet supported in alternate positions, including touch gestures, the Search box, and Ask Copilot.8
    Change the position in Settings > Personalization > Taskbar > Taskbar behaviors. Auto-hidden and touch-optimized taskbars are not currently supported; the smaller taskbar is supported only at the top or bottom.

Taskbar — Smaller Taskbar

For: Insiders in the Beta Channel

  • A smaller taskbar uses smaller icons and less screen height, leaving more room for apps.9
    Set Taskbar size to Small in Settings > Personalization > Taskbar > Taskbar behaviors. The smaller taskbar is currently supported only for top and bottom positions.

Search

For: Insiders in the Beta Channel

  • A new setting lets you choose whether web and Microsoft Store suggestions appear alongside local results.10
    Find the setting in Settings > Privacy & Security > Search.
