Windows 11 Update KB5043145: Key Features & Important Notes

On September 26, 2024, Microsoft rolled out the non-security preview update KB5043145 for Windows 11, available for versions 23H2 and 22H2. This update, which affects OS Builds 22621.4249 and 22631.4249, introduces a range of enhancements and important reminders for users while providing clarity on the future of their Windows editions.

Release Date and Versions​

• Release Date: September 26, 2024
• Version: OS Builds 22621.4249 and 22631.4249

This update indicates a significant milestone as Windows 11 for Home and Pro editions 22H2 is approaching its End of Service (EOS) on October 8, 2024. Users on these editions will receive only security updates until then. Microsoft's guidance is clear: if you desire uninterrupted access to security and non-security updates, upgrading to the latest version of Windows is strongly encouraged.
Notably, Enterprise and Education editions will continue to be supported post-EOS.

What’s New: Key Features and Improvements​

Gradual Rollout​

The new features will be introduced gradually, meaning they might not be available to all users immediately. Here's what's becoming available:

• Taskbar Enhancements:
  • File Sharing: Users can now share local files directly from search result displays in the Taskbar search box.
• Settings Updates:
  • Delivery Optimization Settings: This page has been revamped to align with the modern Windows 11 design, making navigation smoother.
• Windows Share Window:
  • The search feature has been removed from the Windows Share window, streamlining the user experience.
• Lock Screen Notifications:
  • Media controls now occupy a prominent position at the lower center of the lock screen when media is playing, ensuring ease of access during playback.
• Start Menu Improvements:
  • The "Sign out" option is now more accessible directly from the account manager in the Start menu, facilitating easier user switching through a clear list.

Normal Rollouts for Stability​

In addition to the new features, this update addresses several stability issues:

• Microsoft Edge Bugs: Users reported intermittent responsiveness while using IE mode, now rectified.
• Windows Identity Protection: A more user-friendly PIN policy is implemented, affecting Outlook and other encrypted email applications, prompting users for their credentials less frequently.
• Task Manager Bug: Improvements ensure that the Task Manager does not freeze when users transition from high-contrast settings.

Improvements and Reliability​

The update also includes the servicing stack update (KB5043143). A servicing stack update ensures that the underlying component responsible for installing Windows updates becomes more robust and reliable. This is a crucial element in maintaining the health of Windows environments, particularly in enterprise setups.

Known Issues​

As of the update's release, there are no known issues reported by Microsoft. This is a promising sign, as a seamless experience is always preferable after updating.

Installation Guidelines​

To install this update:

1. Navigate to Settings > Update & Security > Windows Update.
2. Check the Optional updates available section for download and installation options.
3. Additionally, users can access the Microsoft Update Catalog for standalone packages.

Removal of Updates​

Should a user need to uninstall a cumulative update (LCU), they can do so using the DISM command-line tools, specifically DISM /online /get-packages to identify the package name.

Final Thoughts: Why This Matters?​

For Windows 11 users, especially those with the 22H2 version, it's a pivotal moment. The update not only introduces new functionality but also highlights the importance of staying up to date with the latest releases to fend off vulnerabilities and ensure a stable computing experience.
Overall, with every update, it's evident that Microsoft is committed to refining the user experience and enhancing system performance. Users are encouraged to actively manage their updates and stay informed about their operating system's lifecycle to ensure a smooth computing experience.
