Microsoft Pushes KB5040442 Update for Win11 with Security and Known Issues

TapTechNews July 10th news, Microsoft today pushed the KB5040442 update to Win11 22H2 and 23H2 users, and the OS internal version number increased to 22621.3880 and 22631.3880.

TapTechNews reminds: The Home and Professional editions of Win11 22H2 will end their service on October 8, 2024. Currently, these versions only receive security updates; however, Microsoft will still continue to support the Enterprise and Education editions after October 8.

The KB5040442 update only includes some security quality updates, mainly related to issues in Windows Installer, Remote Desktop MultiPoint Server, and Remote Authentication Dial-In User Service (RADIUS) protocol.

Windows Installer. When repairing an application, the User Account Control (UAC) will not prompt for credentials. After installing this update, the UAC will prompt for an update. Therefore, it may be necessary to update the automated script. For this, 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.

Remote Desktop MultiPoint Server. A race condition can cause the service to stop responding.

Remote Authentication Dial-In User Service (RADIUS) protocol. This problem is related to the MD5 conflict.

This update also includes some known problems, such as the possible problem (error code 0x80070005) when upgrading from Windows Pro to a valid Windows Enterprise subscription. Microsoft has no solution for the moment and only says that it is working hard to release a solution in the next few weeks.

In addition, installing KB5039302 may lead to unable to view or interact with the taskbar, but this problem will only occur on devices running the Windows N version.
