  • New! Adds improvements for servicing the Secure Boot component of Windows.
  • Addresses an issue that prevents the AppX Deployment Service (AppXSvc) from working after installing certain MSIX apps.
  • Addresses a race condition that occurs early in the boot process that may cause a Stop 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 minutes to 90 minutes for hybrid Azure AD joined Autopilot scenarios. This also resolves a race condition that causes an exception when the timeout occurs.
  • Addresses an issue in which some POS terminals experience occasional operating system startup delays during reboot of up to 40 minutes.
  • Addresses a memory leak issue that affects Windows systems that are used 24 hours a day, every day of the week.
  • 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.
  • Addresses an issue that affects the Title attribute in Microsoft Ege IE mode.
  • Addresses an issue where Mobile Device Management (MDM) policies were not allowed on Windows Enterprise editions that were upgraded to Enterprise using Azure AD joined subscription entitlement.
  • Addresses an issue that could cause video subtitles to be partially cut off.
  • Fixed an issue with video subtitles being misaligned.
  • Addresses an issue that causes Kerberos authentication to fail and the error is “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 causes 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 when copying the security portion of a Group Policy to a machine.
  • Addresses an issue that prevents instantiation of the Microsoft RDP client control, version 11 and later, in a Microsoft Foundation Class (MFC) dialog box.
  • Displays the temperature above the weather icon on the taskbar.
  • Addresses an issue that prevents you from using the minimize, maximize, and close buttons on a maximized application window. This issue occurs because the Notification Center maintains input focus.
  • Addresses an issue that may occur when using Netdom.exe or the Active Directory Domains and Trusts snap-in to list or change name suffix routing. These procedures may fail. The error message is “There are not enough 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 tries to parse outbound approvals only.
  • Addresses an issue that occurs when you map 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 generate a 13A or C2 error.
  • Addresses an issue that corrupts a pool when a client-side caching (CSC) cleanup method fails to remove a resource that has been created.
  • Addresses an issue that could cause the server to hang because the nonpaged pool grows and uses all memory. After a reboot, the same issue recurs when trying to repair the damage.
  • Reduces resource contention overhead in high input/output operations per second (IOPS) scenarios that have many threads competing on a single file.
