Windows 10 and KB5021233, what’s new?

On the occasion of Patch Tuesday of December 2022 Microsoft is releasing cumulative update KB5021233. It targets PCs running Windows 10 21H1, 21H2 and 22H2.

Installing update KB5021233 allows these operating systems to upgrade to version 19042.2364, 19043.2364, 19044.2364, and 19045.2364. These numbers are important because they help ensure that everything went well. You can find them by running “winver.exe” in Run (WIN+R).

The content primarily addresses the correction of 26 security vulnerabilities, including 22 significant, one moderate and three critical. These affect PowerShell CVE-2022-41076 (flaw allowing remote code execution) and SSTP protocol CVE-2022-44676 and CVE-2022-44670 (Flaws allowing remote code execution).

In parallel Microsoft corrects some bugs.

One of the highlights is fixing a problem installing updates from the Microsoft Store. We also have some improvements around search. The search box now appears, by default, in the taskbar when it is placed on the top of the screen or when the “small icons” mode is used. There is also the correction of an issue with some printers. Printouts are misaligned. Daylight saving time in Fiji should now be correct.

Finally a problem that affects the Camera app has been fixed. The app would stop responding when memory was low.

KB5021233 is available through various distribution channels. To install it immediately you can go to Windows Update to manually trigger its download and installation. You can also go to the Microsoft Update Catalog site.
