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 KB5014019. |

After installing this update, some .NET Framework 3.5 apps might have issues or might fail to open. Affected apps are using certain optional components in .NET Framework 3.5, such as Windows Communication Foundation (WCF) and Windows Workflow (WWF) components. |
This issue should be resolved automatically via a Troubleshooter on affected unmanaged devices. If your device is managed by an IT department or with enterprise management tools, you might not get the troubleshooter automatically and might require the below workaround to resolve the issue. For more information on this troubleshooter, please see Windows Update Troubleshooter for repairing .NET Framework components. If you do not automatically receive the troubleshooter, you can mitigate this issue by re-enabling .NET Framework 3.5 and the Windows Communication Foundation in Windows Features. For instructions, please see Enable the .NET Framework 3.5 in Control Panel. Advanced users or IT admins can do this programmatically using an elevated Command Prompt (run as administrator) and running the following commands: |

After installing this update, Windows devices that use certain GPUs might cause apps to close unexpectedly or cause intermittent issues that affect some apps that use Direct3D 9. You might also receive an error in Event Log in Windows Logs/Applications, and the faulting module is d3d9on12.dll and the exception code is 0xc0000094. |
This issue is addressed in KB5014019. If you can't install KB5014019, see the instructions below. This issue is addressed using Known Issue Rollback (KIR). Please note that it might take up to 24 hours for the KIR to propagate automatically to consumer devices and non-managed business devices. Restarting your Windows device might help the KIR apply to your device faster. For enterprise-managed, devices that have installed an affected update and encountered this issue can address it by installing and configuring the special Group Policy listed below. For information on deploying and configuring these special Group Policies, seeHow to use Group Policy to deploy a Known Issue Rollback. Group Policy download with Group Policy name:
Important You must install and configure the Group Policy to address this issue. Please see, How to use Group Policy to deploy a Known Issue Rollback. |

Updated May 27, 2022 After installing updates released May 10, 2022 on your domain controllers, you might see machine certificate authentication failures on the server or client for services such as Network Policy Server (NPS), Routing and Remote access Service (RRAS), Radius, Extensible Authentication Protocol (EAP), and Protected Extensible Authentication Protocol (PEAP). An issue has been found related to how the mapping of certificates to machine accounts is being handled by the domain controller. Note Installation of updates released May 10, 2022, on client Windows devices and non-domain controller Windows Servers will not cause this issue. This issue only affects installation of May 10, 2022, updates installed on servers used as domain controllers. |
Updated May 27, 2022 The preferred mitigation for this issue is to manually map certificates to a machine account in Active Directory. For instructions, please see Certificate Mapping. Note The instructions are the same for mapping certificates to user or machine accounts in Active Directory. If the preferred mitigation will not work in your environment, please see KB5014754—Certificate-based authentication changes on Windows domain controllers for other possible mitigations in the SChannel registry key section. Note Any other mitigation except the preferred mitigations might lower or disable security hardening. This issue was addressed in out-of-band updates released May 19, 2022 for installation on all Domain Controllers in your environment, as well as all intermediary application servers such as Network Policy Servers (NPS), RADIUS, Certification Authority (CA), or web servers which passes the authentication certificate from the client being authenticated to the authenticating DC. If you used any workaround or mitigations for this issue, they are no longer needed, and we recommend you remove them. This includes the removal of the registry key (CertificateMappingMethods = 0x1F) documented in the SChannel registry key section of KB5014754. There is no action needed on the client side to resolve this authentication issue. To get the standalone package for these out-of-band updates, search for the KB number 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. Note The below updates are not available from Windows Update and will not install automatically. Cumulative updates:
Note You do not need to apply any previous update before installing these cumulative updates. If you have already installed updates released May 10, 2022, you do not need to uninstall the affected updates before installing any later updates including the updates listed above. |
