Windows 11 Released KB5012643 – Here’s What’s New and Improved

KB5012643 is now available for Windows 11 with some noteworthy changes and a bunch of additional bug fixes. The update is rolling out via Windows Update and WSUS, but you can also download offline installers for Windows 11 KB5012643. Offline installers are especially useful when users are unable to install the patch via traditional methods.

Windows 11 KB5012643 is an optional cumulative preview update designed to test changes that are set to ship with Patch Tuesday updates in May 2022. Like other optional updates, this cumulative update will not download and install automatically unless you check for updates and start the download manually.

This optional cumulative update isn’t a huge release unlike the March 2022 optional update, but there are several quality improvements. For example, Microsoft added a new feature that would display the temperature above the weather icon that was added to the taskbar with the April 2022 update.

Microsoft fixed an issue where the operating system would incorrectly align video subtitles and fixed another bug where video subtitles would be partially cut off. Microsoft says it has also made changes to prevent users from using Windows window controls, such as the minimize, maximize, and close buttons.

Windows 11 KB5012643 Direct Download Links: 64 Bit

As we mentioned at the beginning, the optional cumulative update for Windows is offered via Windows Update in Settings. If you still want to download the offline installer, which is offered in .msu (MSU package), you can head over to the link above for the Microsoft Update Catalog.

On the Microsoft Update Catalog page, click the Download button and open the .msu link.

For those unaware, the process of downloading the update package is now much easier in browsers like Google Chrome. Previously, Microsoft provided updates in its update catalog via an insecure HTTP connection. As a result, Google has banned users from directly opening the .msu file in the current tab.

Catalog update links are now served through HTTPS and Google no longer prevents users from opening .msu download links.
