The standard rollout encompasses updates for audit, authentication, Country and Operator Settings Asset (COSA), display kernel, network file sharing, performance, shell, Windows Hello, and Windows Search. The update resolves concerns related to auditing privilege usage, authentication, COSA, display kernel, network file sharing, performance, shell, kiosk devices, Windows Hello, and Windows Search.

Releasing Windows 11 Build 22631.5545 to the Release Preview Channel

Hello Windows Insiders, today we’re releasing Windows 11 Build 22631.5545 (KB5060826) to Insiders in the Release Preview Channel on Windows 11, version 23H2 (Build 22631). 

Gradual rollout

The following features and improvements might not be available to all users because they will roll out gradually. Text bolded in brackets indicates the area of the change being documented. Please note that features and improvements that gradually roll out may not begin rolling out right away nor will they immediately show up right away. 

• App defaults] New! We are rolling out some small changes in the EEA region for default browsers via the Set default button in Settings > Apps > Default apps:
  • Additional file and link types will be set for the new default browser, if it registers them.
  • The new default browser will be pinned to the Taskbar and Start menu unless you choose not to pin it by clearing the checkboxes.
  • There is now a separate one-click button for browsers to change your .pdf default, if the browser registers for the .pdf file type.
• [Windows Share] New! When you share links or web content using the Windows share window, you will see a visual preview for that content.

Normal rollout

This update includes the following features and improvements that are rolling out as part of this update. Text bolded in brackets indicates the area of the change being documented.

• [Audit] Fixed: An issue with auditing privilege use created too many security event logs. These logs filled up the system drive and prevented users from signing in.
• [Authentication] Fixed: This update fixes an issue where domain-joined machines running Windows 11 22H2 or 23H2 couldn’t update their account passwords on Windows Server 2025 domain controllers, which led to trust relationship issues.
• Country and Operator Settings Asset (COSA)] Fixed: This update brings profiles up to date for certain mobile operators.
• [Display Kernel] Fixed: An issue that prevented Remote Desktop Protocol (RDP) connections until you restarted your device.
• [Network file sharing] Fixed: This update fixes an issue where workstations and servers might stop responding when connecting to resources located on Server Message Block (SMB) shares.
• [Performance] Fixed: This update addresses an issue that prevented the complete removal of unused language packs and Feature on Demand packages, which previously led to unnecessary storage use and longer Windows Update installation times.
• [Shell] Fixed: This update resolves an issue where kiosk devices might stop responding after being locked and unlocked by an administrator.
• Windows Hello] Fixed: This update fixes an issue that prevented the automatic renewal of expiring certificates in Windows Hello for Business.
• [Windows Search] Fixed: Windows Search responds very slowly—the Search Box can take over 10 seconds to load before you can use it.
