Read on for details on some flaws and how to get this critical update.

Here’s the backstory

Microsoft’s October Patch Tuesday update brings Windows 10 20H2 to build version 19044.2130, Windows 10 21H1 to build version 19043.2130 and Windows 10 21H2 to build version 19044.2130. While the update number depends on your build version, the files are identical.

The update corrects 84 flaws, with Microsoft labeling 13 as critical. It also includes a fix for two zero-day exploits, but a third exploit remains a problem.
