Windows 11 KB5012643

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

Windows 11 KB5012643 is an optional cumulative preview update and it is designed to test the changes set to ship with May 2022 Patch Tuesday updates. Like the rest of the optional updates, this cumulative update won’t download and install automatically unless you check for updates and manually start the download.

This optional cumulative update is not a huge release unlike the March 2022 optional update, but there are several quality improvements. For example, Microsoft has added a new feature that would display the temperature on top of the weather icon which was added to the taskbar with the April 2022 Update.

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