Improvements

This cumulative security update contains improvements that are part of update KB5039260 (released June 11, 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.

  • [DST] The official name of the former “Republic of Turkey” is changed to Republic of Türkiye in English. For more information about DST changes, see the Daylight Saving Time & Time Zone Blog.

  • [IME] In some scenarios, an Input Method Editor (IME) will either not show or show in an incorrect position.

  • [RADIUS protocol] A security vulnerability exists in the Remote Authentication Dial-In User Service (RADIUS) protocol related to MD5 collision problems. For more information, see KB5040268.

  • [Windows Installer] When the installer 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 might have to update your Automation scripts and add the Shield icon. This 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. For more information, see:

For more information about the resolved security vulnerabilities, please refer to the Deployments | Security Update Guide and the July 2024 Security Updates.

We are currently not aware of any issues with this update.

How to get this update
