Windows 8.1 reached the end of support (EOS) on January 10, 2023, at which point technical assistance and software updates are no longer provided. If you have devices running Windows 8.1, we recommend upgrading them to a more current, in-service, and supported Windows release.

-
[User Account Control (UAC)] When the Windows Installer repairs an application, the UAC does not prompt for your credentials. After you install this update, it will prompt for them. Because of this, you might have to update your automation scripts. Additionally, you should add the Shield icon to indicate that your automation scripts require full administrator access. To turn off the UAC prompt, set the HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Installer\DisableLUAInRepair registry value to 1. For more information, see:
-
[Remote Desktop Services (RDS)] Fixes an issue in which RDS would stop responding.
-
[Dual boot of Windows and Linux (known issue)] Linux might fail to start up after installing the August 2024 Windows update. 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.

Known issues in this update
Symptom |
Next Step |
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. |
This issue is fixed in update KB5044343. |
For the current status of any past known issue, see the Windows Server 2012 Known Issues page.
