Microsoft releases KB5011563 for Windows 11 as an optional update with long list of fixes

Microsoft has just released a new build 22000.593 (KB5011563) as an optional "C" update for Windows 11. You may remember that this same update was released to the Beta Channel two weeks ago, and although this is an optional update, it will eventually be offered through the Patch Tuesday release cycle in around two weeks time.

As such the long list of improvements and fixes, shown below, are unchanged.

  • New! We displayed up to three high priority toast notifications simultaneously. This feature is for apps that send notifications for calls, reminders, or alarms using Windows notifications in the OS. As a result, up to four toast notifications might appear simultaneously–three high priority notifications and one normal priority notification.
  • We fixed an issue that turns off auto-startup for Universal Windows Platform (UWP) apps after you upgrade the OS.
  • We fixed an issue that causes SystemSettings.exe to stop working.
  • We fixed an issue that affects searchindexer.exe and prevents Microsoft Outlook’s offline search from returning recent emails.
  • We fixed an issue that increases the startup time for Windows. This issue occurs because a UI thread in a networking API stops responding when a 5G wireless wide area network (WWAN) device is slow to wake up.
  • We fixed a memory leak in the wmipicmp.dll module that causes a lot of false alarms in the System Center Operations Manager (SCOM) datacenter monitoring system.
  • We fixed an issue that incorrectly returns the Execution Policy settings from the registry.
  • We fixed an issue in which modern browsers fail to correctly render HTML that is generated by gpresult/h.
  • We fixed an issue that causes an “Access denied” exception for a file during a PowerShell test for AppLocker.
  • We fixed an issue that causes the Remote Desktop Service (RDS)server to become unstable when the number of signed in users exceeds 100. This prevents you from accessing published applications using RDS on Windows Server 2019.
  • We fixed an issue that returns an error message when you browse for a domain or organizational unit (OU). This issue occurs because of improper zeroing out of memory.
  • We fixed an issue that causes the Group Policy Management Console to stop working after you close it. The system logs Application Error Event ID 1000 and the error, 0xc0000005 (STATUS_ACCESS_VIOLATION); the failing module is GPOAdmin.dll.
  • We fixed an issue that might cause the Group Policy Service to stop processing telemetry information for Group Policy Registry Preferences.
  • We fixed a stop error (0xD1, DRIVER_IRQL_NOT_LESS_OR_EQUAL) in the DirectX kernel component.
  • We fixed an issue that might cause Kerberos.dll to stop working within the Local Security Authority Subsystem Service (LSASS). This occurs when LSASS processes simultaneous Service for User (S4U) user-to-user (U2U) requests for the same client user.
  • We fixed an issue that affects the Key Distribution Center (KDC) Proxy. The KDC Proxy cannot properly obtain Kerberos tickets for signing in to Key Trust Windows Hello for Business.
  • We added support for Microsoft Account (MSA) Pass-through scenarios in Azure Active Directory(AAD) Web Account Manager (WAM).
  • We fixed an issue that logs Event ID 37 during certain password change scenarios, including failover cluster name object (CNO) or virtual computer object (VCO) password changes.
  • We fixed an issue that prevents the User Account Control (UAC) dialog from correctly showing the application that is requesting elevated privileges.
  • We fixed an issue that might cause a Microsoft OneDrive file to lose focus after you rename it and press the Enter key.
  • We returned the corresponding Settings page when you search for the word widgets.
  • We fixed an issue that prevents Event 4739 from displaying the new values of certain attributes after a policy change.
  • We fixed an issue that causes the Move-ADObject command to fail when you move computer accounts across domains. The error message is, “Multiple values were specified for an attribute that can have only one value”.
  • We fixed an issue that prevents you from accessing Server Message Block (SMB) shares using an IP Address when SMB hardening is enabled.
  • We fixed an issue that causes stop error 0x1E in the SMB Server (srv2.sys).
  • We fixed an issue that causes a mismatch between NetBIOS and DNS Active Directory domain names when you create a cluster.

There's just one known issue to be aware of:

After installing the Windows updates released January 11, 2022 or later Windows versions on an affected version of Windows, recovery discs (CD or DVD) created by using the Backup and Restore (Windows 7) app in Control Panel might be unable to start.

Recovery discs that were created by using the Backup and Restore (Windows 7) app on devices which have installed Windows updates released before January 11, 2022 are not affected by this issue and should start as expected.

Note No third-party backup or recovery apps are currently known to be affected by this issue

There is no official workaround for the above issue yet, but Microsoft says they are working on it.

You can grab this optional update by heading to Settings > Windows Update and if not already available, Check for updates. In the Optional updates available area, you’ll find the link to download and install the update. Or you can manually download the update for your edition through this Microsoft Catalog link.
