Today, Microsoft has released Windows 11 Insider Preview Build 22621.1028 and Build 22623.1028 to insiders in the Beta Channel.

  • Build 22623.1028= New features rolling out.
  • Build 22621.1028 = New features off by default.

Fixed in Build 22623.1028

[General]

  • Made another fix to address explorer.exe crashing repeatedly in safe mode.

[Taskbar & System Tray]

  • Fixed an issue where, with the system tray design updates, auto-hiding the taskbar would stop working after you had interacted with the hidden icons fly-out.
  • Made a small refinement for tablet-optimized taskbar users to make it a bit easier to expand the taskbar without invoking the Start menu.
  • Fixed an issue that could lead to the taskbar jump lists and preview thumbnails not appearing in the correct position for Insiders with 2-in-1 PCs.
  • Improved the transition animation when switching between collapsed and expanded views of the tablet-optimized taskbar.
  • The tablet-optimized taskbar should collapse more reliably now after launching an app from the Start menu.
  • Fixed an explorer.exe crash when using Alt + F4 with the show hidden icons fly-out in the system tray open.
  • Updated the battery icon’s tooltip to let you know if your device is charging slowly.
  • Fixed an issue causing the top half of the media controls in Quick Settings to be missing sometimes.
  • Fixed a GDI handle leak in recent builds related to receiving certain types of notifications. This could cause UI issues or explorer.exe crashes for Insiders who receive a lot of notifications.
  • Fixed an issue that was causing the NVIDIA icon in the system tray to show empty notifications.

[Search]

  • Fixed an issue causing the search not to work in the previous flight for Insiders with Arm64 PCs.

[Settings]

  • Fixed an issue where the sleep recommendation on the Energy Recommendations page and Battery & Power page was sometimes inconsistent.

[Task Manager]

  • Task Manager colors in light and dark should display correctly now for people with their mode set to Custom.

Fixes for Both Build 22621.1028 & Build 22623.1028

  • We fixed an issue that affected some games and applications. This issue was related to GPU performance debugging features. This lowered the expected game performance.

Known issues 

[General]

[Taskbar & System Tray]

  • The taskbar takes longer than expected to transition to the touch-optimized version when switching between desktop posture and tablet posture.

[Task Manager]

  • [NEW] When using the search box at the top of Task Manager, Task Manager may become unresponsive.
  • Filtering by publisher name does not match correctly on the Processes page.
  • Some services may not show in the Services page after filtering is applied.
  • If a new process is starting while a filter is set, then that process may appear for a split second in the filtered list.
  • Some dialogs may not render in the correct theme when applied from the Task Manager Settings page.
  • The data content area of the Processes page may flash once when theme changes are applied in the Task Manager Settings page.
