Windows 11 build 22623.1028

These are the fixes specific to build 22623.1028:


• 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 flyout.
• 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 which 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 flyout 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. 


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


  • 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.
