Exploring the Latest Features in Windows 11 with Updates KB5031358 and KB5031354

The major monthly maintenance for October 2023 introduces two cumulative updates for Windows 11, namely KB5031358 and KB5031354. The first is designed for 21H2, while the second is tailored for 22H2.

This Patch Tuesday holds significant importance for the operating system. It marks the final maintenance update for Windows 11 21H2, as Microsoft is discontinuing support for this version. Simultaneously, Windows 11 22H2 incorporates all the new features of Moment 4. These features are not unfamiliar, as they have been accessible through an optional update for some days. Now, users can expect automatic downloads and installations.

Regarding security, Microsoft fixes 75 vulnerabilities, 12 of which are considered critical. They concern the Layer 2 Tunneling protocol ( CVE-2023-38166 , CVE-2023-41765 , CVE-2023-41767 , CVE-2023-41768 , CVE-2023-41769 , CVE-2023-41770 , CVE-2023-41771 , CVE-2023-41773 , CVE-2023-41774 ), Microsoft Message Queuing ( CVE-2023-35349 , CVE-2023-36697 ), and the Virtual Trusted Platform module ( CVE-2023-36718 ). All this little world allows remote code execution.

Upon installation, the operating system will advance to version 22000.2538. This numerical identifier serves as a straightforward means to verify the success of the installation. You can locate it by launching winver.exe in “Run” (WIN+R).

All the contents of the optional update for September 2023 (KB5030301) are present. The noteworthy highlight is the resolution of a bug affecting Excel. This bug can potentially cause the application to crash when attempting to share a PDF file in Excel.

Windows 11 22H2 et KB5031354

We are facing an important update. Its installation allows the OS to upgrade to version 22621.2428. It offers all the content of the optional update KB5030310 for September 2023. It includes all the new features of Moment 4.

Here are the three most notable facts.

Perhaps one of the most notable advancements is the introduction of Copilot, an AI-powered assistant. Its goal is to make the OS more user-friendly and intelligent. Its capabilities are currently limited to a few commands, such as taking screenshots or switching to dark mode. At the same time, Windows 11 is enriched with a new backup application designed to facilitate the inclusion of new content on OneDrive. This will apply to certain folders, settings, and customizations. This application is not intended to compete with specialized backup utilities.

Finally, the file explorer interface benefits from significant work with modifications, notably a movement of the address and the toolbar in order to offer an environment close to that of a web browser. The “Gallery” module is dedicated to managing images and snapshots, adopting an approach similar to the chronological display of the Photos application. The information pane shows larger thumbnails and a new sharing option.
