Improvements and fixes

Main fixed:

According to the official release note, Microsoft has fixed the error with message:  

“Error: 0x20EF. The directory service encountered an unknown failure”

An issue whereby Lightweight Directory Access Protocol operation could fail if the operation contains the Sam Account Name and User Account Control attributes.

Additionally, Microsoft has fixed some issues as below:

  • Updates daylight savings time to start in February 2022 instead of March 2022 in Jordan. 

Special patches for some versions in this update release:

For KB5010359 (OS Build 14393.4946) for Windows 10 version 1607

  • Updates the phone number for Windows Activation for locales that have the wrong phone number.
  • Fixed the error, “IRQL_NOT_LESS_OR_EQUAL”.
  • Fixed issue that causes the improper cleanup of Dynamic Data Exchange (DDE) objects. This prevents session teardown and causes a session to stop responding.
  • Fixed access violation in IKEEXT.dll that occurs on Always On VPN (AOVPN) and DirectAccess servers. The exception code is 0xC000005.
  • Fixed issue that affects Administrative Template settings you configure using a Group Policy Object (GPO). When you change the value of the policy setting to NOT CONFIGURED, the system fails to remove the previous setting. This issue is most noticeable for roaming user profiles.
  • Fixed a memory leak that occurs when you call WinVerifyTrust(). This issue occurs if verification fails for the first signature of a file that has multiple signatures.
  • Fixed a known issue that affects versions of Windows Server that are in use as a Key Management Services (KMS) host. Client devices running Windows 10 Enterprise LTSC 2016 might not activate. This issue only occurs when using a new Customer Support Volume License Key (CSVLK) and after installing updates released April 22, 2021 or later.
  • Adds an audit event to Active Directory domain controllers that identifies clients that are not compliant with RFC 4456. For more information, see KB5005408: Smart card authentication might cause print and scan failures.
  • 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.

For KB5010358 (OS Build 10240.19204) for Windows 10 initial version released July 2015

  • Fixed the error, “IRQL_NOT_LESS_OR_EQUAL”.
