Improvements
This security update includes improvements. Below is a summary of the key issues that this update addresses when you install this KB. If there are new features, it lists them as well. The bold text within the brackets indicates the item or area of the change we are documenting.
-
[AppContainer] Printers do not work as you expect when you use them in a restricted setting, like AppContainer.
-
[BitLocker] You might not be able to decrypt a BitLocker data drive. This occurs when you move that drive from a newer version of Windows to an older version.
-
[Windows Installer] When it repairs an application, the User Account Control (UAC) does not prompt for your credentials. After you install this update, the UAC will prompt for them. Because of this, you must update your automation scripts. Application owners must add the Shield icon. It indicates that the process requires full administrator access. To turn off the UAC prompt, set the HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Installer\DisableLUAInRepair registry value to 1. The changes in this update might affect automatic Windows Installer repairs; see Application Resiliency: Unlock the Hidden Features of Windows Installer.
-
[Windows Server 2019 (known issue)] Some devices slow down, stop responding, and have high CPU usage. This is most likely to occur with Cryptographic Services. A few companies report that the issue occurs when antivirus software scans the %systemroot%\system32\catroot2 folder for Windows updates.
-
[Dual boot of Windows and Linux (known issue)] Linux might fail to start up when you turn on dual-boot setup for Windows and Linux on your device. The error message is, “Verifying shim SBAT data failed: Security Policy Violation. Something has gone seriously wrong: SBAT self-check failed: Security Policy Violation.” See the full guidance in CVE-2022-2601 and CVE-2023-40547.

Windows 10 servicing stack update (KB5043126) - 17763.6289
This update makes quality improvements to the servicing stack, which is the component that installs Windows updates. Servicing stack updates (SSU) ensure that you have a robust and reliable servicing stack so that your devices can receive and install Microsoft updates.
Known issues in this update
Symptom |
Workaround |
---|---|
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). Next step: We are working on a resolution and will provide an update in an upcoming release. |
How to get this update
