Improvements
This cumulative security update contains improvements that are part of update KB5040485 (released July 9, 2024). The following is a summary of the key issues that this update addresses. The bold text within the brackets indicates the item or area of the change we are documenting.
-
[NetJoinLegacyAccountReuse] Removes this registry key. For more information, see KB5020276.
-
[BitLocker (known issue)] A BitLocker recovery screen shows when you start up your device. This occurs after you install the July 9, 2024, update. This issue is more likely to occur if device encryption is on. Go to Settings > Privacy & Security > Device encryption. To unlock your drive, Windows might ask you to enter the recovery key from your Microsoft account.
-
[Secure Boot Advanced Targeting (SBAT) and Linux Extensible Firmware Interface (EFI)] This update applies SBAT to systems that run Windows. This stops vulnerable Linux EFI (Shim bootloaders) from running. This SBAT update will not apply to systems that dual-boot Windows and Linux. After the SBAT update is applied, older Linux ISO images might not boot. If this occurs, work with your Linux vendor to get an updated ISO image.
-
[Domain Name System (DNS)] This update hardens DNS server security to address CVE-2024-37968. If the configurations of your domains are not up to date, you might get the SERVFAIL error or time out.
For more information about the resolved security vulnerabilities, please refer to the Deployments | Security Update Guide and the August 2024 Security Updates.

After installing the Windows update released on or after July 9, 2024, Windows Servers might affect Remote Desktop Connectivity across an organization. This issue might occur if legacy protocol (Remote Procedure Call over HTTP) is used in Remote Desktop Gateway. Resulting from this, remote desktop connections might be interrupted. This issue might occur intermittently, such as repeating every 30 minutes. At this interval, logon sessions are lost and users will need to reconnect to the server. IT administrators can track this as a termination of the TSGateway service which becomes unresponsive with exception code 0xc0000005. |
To work around this issue, use one of the following options: Option 1: Disallow connections over pipe, and port \pipe\RpcProxy\3388 through the RD Gateway. This process will require the use of connection applications, such as firewall software. Consult the documentation for your connection and firewall software for guidance on disallowing and porting connections. Option 2: Edit the registry of client devices and set the value of RDGClientTransport to 0x00000000 (0) In Windows Registry Editor, navigate to the following registry location: HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client Find RDGClientTransport and set its value to 0 (zero). This changes the value of RDGClientTransport to 0x00000000 (0). We are working on a resolution and will provide an update in an upcoming release. |

After installing this security update, you might face issues with starting Linux if you have enabled the dual-boot setup for Windows and Linux on your device. Resulting from this issue, your device might fail to start Linux and show the error message “Verifying shim SBAT data failed: Security Policy Violation. Something has gone seriously wrong: SBAT self-check failed: Security Policy Violation.” This August 2024 Windows security update applies a Secure Boot Advanced Targeting (SBAT) setting to devices that run Windows to block old, vulnerable boot managers. This SBAT update will not be applied to devices where dual-booting is detected. On some devices, the dual-boot detection did not detect some customized methods of dual-booting and applied the SBAT value when it should not have been applied. |
The Windows update (KB5043125) released in September 2024 does not contain the settings that caused this issue. On Windows-only systems, after installing the September 2024 or later update, you can set the registry key documented in CVE-2022-2601 and CVE-2023-40547 to ensure the SBAT security update is applied. On systems that dual-boot Linux and Windows, there are no additional steps necessary after installing the September 2024 or later update. |
For the current status of any past known issue, see the Windows Server 2012 Known Issues page.
