Microsoft has released a new build of Windows 11 for Windows Insiders on the dev channel. Build 23521 has improvements for Windows 365 users, the system tray, Task Manager and Windows Spotlight.

Windows 365

Windows 365 Switch enables you to move between Windows 365 Cloud PC using the Task View in Windows 11

Windows Copilot

Windows Insiders who are managed by AAD can now use Windows Copilot

Taskbar & System Tray

Microsoft have made it easier to enable never combined mode on the taskbar. You can turn never combined mode on by simply adjusting “Combine taskbar buttons and hide labels” to never.

Task Manager Settings

Microsoft has updated the Task Manager Settings to match the Windows 11 style.

Dynamic Lighting

If you have Dynamic Lighting you can now instantly sync your Windows accent colour with the devices around you with the “Match my Windows accent color” toggle under “Effects” for Dynamic Lighting via Settings > Personalization > Dynamic Lighting.

Widgets Update: Pin widgets board open

There is an update to Widgets for Windows Insiders in the Canary and Dev Channels that lets you pin the widgets board open, so your widgets board is always just a glance away. To pin the board open, simply click the pin icon in the top right corner of the board. Once your board is pinned open, the widgets board will no longer light dismiss.

  • Fixed an issue where you couldn’t drag a file out of an archived folder to extract it with one of the newly supported archive formats.

  • When trying to extract one of the new archive formats and the file is password encrypted, it will now show a message saying this isn’t currently supported.

Known issues

  • We’re investigating reports that the taskbar isn’t loading for some Insiders when logging into their PC after installing this build. See this forum post for more details and workaround options.
