Build 22623.1028 fixes


  • Another adjustment was made to handle explorer.exe frequently crashing in safe mode.

[System Tray & Taskbar]

  • Fixed a problem where, after interacting with the hidden icons flyout, auto-hiding the taskbar would stop working with the system tray design upgrades.
  • It has been slightly simplified for taskbar users who are using tablets to expand the taskbar without calling up the Start menu.
  • Fixed a problem that could have prevented Insiders using 2-in-1 PCs from seeing the taskbar jump lists and preview thumbnails in the proper locations.
  • The tablet-friendly taskbar’s transition animation between its collapsed and enlarged versions has been improved.
  • After opening an app from the Start menu, the tablet-optimized taskbar ought to collapse more consistently from this point forward.
  • Explorer.exe no longer crashes when Alt + F4 is pressed when the display hidden icons flyout is active in the system tray.
  • The tooltip for the battery icon has been updated to inform you if your smartphone is charging slowly.
  • a problem that occasionally prevented the top half of the media controls from appearing in Quick Settings has been fixed.
  • Recent builds that dealt with receiving particular types of alerts had a GDI handle leak that was fixed. Insiders who get a lot of notifications may have UI problems or explorer.exe crashes as a result of this.
  • Fixed a problem that was causing the NVIDIA icon to display empty notifications in the system tray.


  • Fixed a problem that prevented Insiders using Arm64 PCs in the prior flight from utilising search.


  • Fixed a problem where the sleep advice on the Battery & Power and Energy Recommendations pages was occasionally inconsistent.

[Project Manager]

If your mode is set to Custom, Task Manager colours in light and dark should now appear correctly.

Corrections for BOTH builds 22621.1028 and 22623.1028

  • We resolved a problem that affected a few software programmes and games. This problem involved features for debugging GPU performance. The anticipated game performance was so decreased.

[System Tray & Taskbar]

  • When switching between the tablet and desktop positions, the taskbar takes longer than anticipated to update to the touch-optimized version.

[Project Manager]

  • [NEW] Task Manager can stop responding when you use the search box up top.
  • On the Processes page, the publisher name filter does not match properly.
  • After filtering is used, some services might not appear on the Services page.
  • A new process may briefly appear in the filtered list if it is starting while the filter is active.
  • When using the Task Manager Settings page to apply a theme, some dialogue boxes might not display properly.
  • When theme changes are made in the Task Manager Settings page, the data content area of the Processes page may flash once.
  • For some Insiders, there are no apps listed on the Task Manager tab for startup apps. Please utilise Settings > Apps > Startup for the time being if you are affected.
