Windows 11 KB5012643 is now available for download for all users, with a few notable changes and a host of additional bug fixes. The new update is distributed via Windows Update and WSUS as always. However, you can also manually install Windows 11 KB5012643 via offline installers. Offline installation files can be useful when users are unable to install the patch using normal methods.
Windows 11 KB5012643 update arrived as an optional cumulative preview update and is set to test the changes expected to arrive with the Tuesday May 2022 Update. Like other optional updates, this cumulative update is not automatically downloaded and installed on your system unless you check and manually initiate the download.
This isn’t a huge release, but a few quality improvements have been made. For example, Microsoft added a new feature to display the temperature above the weather icon added to the taskbar with the April 2022 Update.
Microsoft fixed an issue where the operating system misaligned video subtitles and another bug where video subtitles were partially cut off. However, changes have been made so that users can use Windows window controls such as minimize, maximize, and close buttons more efficiently. Let’s take a closer look at what awaits us:
- Fixed an issue that could cause video subtitles to be partially cut off.
- Fixed an issue that misaligned video subtitles.
- Temperatures are now displayed above the weather icon in the taskbar.
- Fixed a memory leak issue affecting Windows systems that are in use 24 hours a day, weekdays.
- Fixed an issue that prevented you from using the minimize, maximize, and close buttons in a maximized application window.

- Fixed an issue where the root domain’s primary domain dendollarsealer (PDC) was generating warning and error events in the System log.
- Fixed an issue when you mapped a network drive to a Server Message Block version 1 (SMBv1) share. With the issue, users were unable to access that network drive after restarting the operating system.
- Fixed issue affecting SMB multi-channel connection that could generate error 13A or C2.
- Fixed an issue that damaged the pool when the Client Side Caching (CSC) cleanup method could not delete a created resource.

- Reduced load in high input/output operations per second (IOPS) scenarios when multiple threads are working on a single file.
This optional update is available through Windows Update in Settings. However, you can download the .msu offline install package from the Microsoft Update Catalog links below.
Additionally, the update package download is now much easier in browsers such as Google Chrome. Previously, Microsoft offered updates in the Update Catalog via the insecure connection HTTP. As a result, Google blocked users from opening the .msu file directly in the current tab. Update links are now served over HTTPS and Google no longer prevents users from opening .msu download links.
