KB5077374: Overview with user sentiment and feedback

Overview

This update makes improvements to Windows setup binaries or any files that setup uses for feature updates in Windows 11, version 23H2. The update addresses issues related to Secure Boot, replacing the 2011 signed bootmgfw.efi with the 2023 signed bootmgfw.efi. It also fixes an issue where the KDNET utility DLLs (kdstub.dll and kdnet.dll) might stop responding when Boot Manager (bootmgr) debugging is enabled during Windows start.

General Purpose

The main purpose of this update is to improve the Windows setup and recovery process for Windows 11 version 23H2. The update addresses Secure Boot related changes, replacing older signed bootmgfw.efi files with newer ones. It also fixes an issue with the KDNET utility DLLs that could cause them to stop responding during Windows boot. These improvements help ensure a smoother and more reliable setup and recovery experience for Windows 11 23H2 users.

General Sentiment

Overall, the sentiment around this update seems positive, as it addresses important setup and recovery related issues in Windows 11 version 23H2. The Secure Boot changes and KDNET fix are likely welcomed improvements that will help provide a more stable and reliable experience for users. However, some caution is warranted around the Secure Boot changes, as resetting the Secure Boot database or toggling Secure Boot could potentially lead to issues. Users are advised to be aware of the consequences and create Secure Boot recovery media if needed.

Known Issues

• The update replaces the 2011 signed bootmgfw.efi with the 2023 signed bootmgfw.efi on devices that already have the Windows UEFI CA 2023 certificate in their Secure Boot Signature Database (DB). Users should be aware of the consequences of resetting the DB or toggling Secure Boot, as this can cause a "Secure Boot violation" issue. In those rare cases, the solution is to create the Secure Boot recovery media.
