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.

As mentioned at the outset, Windows cumulative optional update
is offered via Windows Update in Settings. If you still want to

longer blocks users from opening the .msu download links.
