Known issues in this update

Symptom

Workaround

After installing updates released January 11, 2022 or later, apps that use the Microsoft .NET Framework to acquire or set Active Directory Forest Trust Information might have issues. The apps might fail or close or you might receive an error from the app or Windows. You might also receive an access violation (0xc0000005) error. 

Note for developers Affected apps use the System.DirectoryServices API.

To resolve this issue manually, apply the out-of-band updates for the version of the .NET Framework used by the app.

Note These out-of-band updates are not available from Windows Update and will not install automatically. To get the standalone package, search for the KB number for your version of Windows and .NET Framework in the Microsoft Update Catalog. You can manually import these updates into Windows Server Update Services (WSUS) and Microsoft Endpoint Configuration Manager. For WSUS instructions, see WSUS and the Catalog Site. For Configuration Manger instructions, see Import updates from the Microsoft Update Catalog

For instructions on how to install this update for your operating system, see the KB articles listed below:

  • Windows Server 2022: 

  • Windows Server 2019: 

  • Windows Server 2016: 

  • Windows Server 2012 R2: 

  • Windows Server 2012:

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

This issue is addressed in KB5013952.
