KB5013943 Update Improvements

  • Adds improvements for servicing the Windows Secure Boot component.
  • Addresses an issue that prevents the AppX Deployment Service (AppXSvc) from working after installing certain MSIX apps.

  • Fixes a race condition that occurs early in the boot process that can cause a fatal error.
  • Enhances the Autopilot client to address updated Trusted Platform Module (TPM) features that support self-deployment and pre-provisioning scenarios.
  • Changes the Azure Active Directory (Azure AD) registration timeout from 60 to 90 minutes for Azure AD joined hybrid Autopilot scenarios. This also fixes a race condition that causes an exception to time out.
  • Addresses an issue where some POS terminals experience occasional delays in booting the operating system upon reboot of up to 40 minutes.
  • Addresses a memory leak issue that affects Windows systems that are used 24 hours a day.
  • Addresses an issue that affects Dynamic Host Configuration Protocol (DHCP) option 119 (domain search option) by preventing the use of the connection-specific DNS suffix search list.
  • Fixed an issue affecting the Title attribute in Microsoft Age IE mode.
  • Addresses an issue where Mobile Device Management (MDM) policies were not allowed in Windows Enterprise editions that were upgraded to Enterprise using Azure AD joined subscription entitlement.
  • Fixes an issue that could cause video subtitles to be partially cut off.
  • Fixes an issue with incorrect alignment of video subtitles.
  • Addresses an issue that causes Kerberos authentication to fail with error “0xc0030009 (RPC_NT_NULL_REF_POINTER)”. This occurs when a client computer attempts to use Remote Desktop Protocol (RDP) to connect to another computer while Remote Credential Guard is enabled.
  • Addresses an issue that caused Windows to go into BitLocker recovery after a maintenance update.
  • Addresses an issue that prevents the Endorsement Key (EK) certificate from being retrieved from the TPM device.
  • Fixes an issue that could fail to copy the security portion of a Group Policy to a computer.
  • Addresses an issue that prevents the Microsoft RDP client control (version 11 and later) from being instantiated in a Microsoft Foundation Class (MFC) dialog.
  • Displays the temperature at the top of the taskbar weather icon.
  • Fixed an issue that prevented you from using the minimize, maximize, and close buttons in a maximized application window. This issue occurs because the Notification Center maintains input focus.
  • Fixed an issue that could occur when using netdom.exe or the Active Directory Domains and Trusts snap-in to list or change name suffix routing. Errors can occur in these procedures. The error message is “Insufficient system resources to complete the requested service.” This issue occurs after installing the January 2022 security update on the Primary Domain Controller Emulator (PDCe).
  • Addresses an issue that causes the primary domain controller (PDC) of the root domain to generate Warning and Error events in the System log. This issue occurs when the PDC incorrectly attempts to review outbound approvals only.
  • Addresses an issue that occurs when mapping a network drive to a Server Message Block version 1 (SMBv1) share. After restarting the operating system, you cannot access this network drive.
  • Addresses an issue that affects a multi-channel SMB connection and may result in a 13A or C2 error.
  • Fixed an issue that corrupted a pool when a client-side caching (CSC) cleanup method failed to remove a created resource.
  • Fixed an issue that could cause the server to crash as the non-paged pool grows and uses all memory. After restarting, the same issue recurs when trying to repair the damage.
  • Reduces resource contention overhead in high input/output per second (IOPS) scenarios that have many threads competing on a single file.

  • Fixes a known issue that could cause screen flickering if we started the PC in safe mode. Components that depend on explorer.exe, such as File Explorer, Start Menu, and Taskbar, may be affected and appear unstable.

Also, how could it be otherwise in the case of a “Patch Tuesday”, this update KB5013943 includes a series of security improvements specified by Microsoft.
