These are the fixes specific to build 22623.875:

Tablet-optimized Taskbar

  • Tablet-optimized taskbar which began rolling out with Build 22623.730 is now available to all Windows Insiders in the Beta Channel. The System Tray improvements that began rolling out with Build 22623.746 that include drag and drop is still rolling out so not all Insiders in the Beta Channel will see this right away.


  • The change that adds Task Manager to the context menu when right-clicking on the taskbar is now available to all Windows Insiders in the Beta Channel.
  • You can now swipe up from within the taskbar with a pen to expand the tablet-optimized taskbar.
  • The show hidden icons panel in the system tray should no longer block context menus opened after it.

Windows 11 builds 22623.875 and 22621.875

These are the fixes that the Windows team is shipping with builds 22623.875 and 22621.875.

  • enhanced the backup experience when using your Microsoft Account (MSA). Some devices might notice visual treatments for this enhancement. This is available to a small audience initially and deploys more broadly in the months that follow.
  • Fixed an issue that might affect some types of Secure Sockets Layer (SSL) and Transport Layer Security (TLS) connections. These connections might have handshake failures. For developers, the affected connections are likely to send multiple frames followed by a partial frame with a size of less than 5 bytes within a single input buffer. If the connection fails, your app will receive the error, “SEC_E_ILLEGAL_MESSAGE”.
  • Stopped the start of daylight saving time in Jordan at the end of October 2022. The Jordan time zone will permanently shift to the UTC + 3 time zone.
  • Fixed an issue that affects transparency in layered windows. This occurs when you are in High-Definition remote applications integrated locally (RAIL) mode.

Microsoft is looking into problems with the tablet-optimized Taskbar as part of the known issues.
