Windows 11 KB5017389 (22H2) is the first optional preview update for Windows 11 that includes a series of improvements and bug fixes. It was released to the public alongside the official Windows 11 22H2 update. This update is available as an offline setup package and can be downloaded from the Windows Update Catalog or received via Windows Update (WU).

KB5017389 is compatible only with Windows 11 version 22H2 and yields Windows 11 Build 22621.608. It includes several fixes and enhancements, improving system performance and addressing various known issues.

To apply the changes, you will need to restart your system. The installation process might take longer than five minutes, but only one restart is required for the update to take effect.

This update will be made publicly available during the October 2022 Patch Tuesday cycle. If you’d like to download KB5017389, it is available for 64-bit systems via the Update Catalog or direct links to file hosting sites.

Windows 11 KB5017389 (Version 22621.608) brings several updates and fixes, including the introduction of the new notification badging feature for widgets on the taskbar. This feature ensures users can easily track unread alerts in their widgets. When users click on the notice badge, they can view more information about the alert, and clicking the banner takes them to the forum’s main page.

The update also addresses multiple issues, such as the unexpected cessation of Microsoft Store downloads, and the problem with IE mode causing all active tabs to refresh during session switches. Microsoft also removed the requirement for installing apps not digitally signed by the Microsoft Store.

Other fixes in this update include:

• Resolution of a printing issue that caused a second print queue to arise, halting the primary print queue from processing jobs.
• Strengthened Windows Defender’s MSHTML and ActiveX rules with Application Control, preventing circumvention.
• Fixed issues with the Miracast interface and LogonUI.exe freezing, which allowed users to bypass the lock screen and proceed to the credentials screen.
• Resolved issues with Dual SIM functionality, ensuring calls can be made without first selecting a SIM card.

To install this update, download the .msu files from the Microsoft Update Catalog, select the appropriate version for your system, and run the downloaded files.

Windows 11 KB5017389 (Version 22621.608) includes important bug fixes, such as resolving a memory leak caused by the FindNextFileNameW() function, fixing issues with robocopy, and preventing “Blue Screen of Death” errors when using OneDrive.

It also addresses issues with Roaming User Profiles. It ensures restored settings reflect user preferences, and fixes memory leaks caused by mounting network drives.

However, Microsoft has acknowledged that some users have faced issues with installation. Despite the update being offered, certain users have reported failed installations, with errors occurring during the update process.

In these cases, users have attempted to fix the issue using tools like DISM and sfc /scannow, with no signs of corruption, but still faced problems.

Despite these reports, Microsoft claims it has not received any significant complaints regarding critical OS issues and remains unaware of any other major problems caused by the update.

If you’re encountering issues during the installation process, try using the .msu offline installer that you downloaded from the Microsoft Update Catalog. This can often resolve installation problems by bypassing any potential issues with the automatic Windows Update process. Simply run the .msu file to manually install the update.
