Changes included in the February Patch Tuesday Updates

Windows 10, version 20H2

As of the writing of this article, Windows 10 v20H2 is the latest major version of Windows 10, and as such has the most experimental features on it.

Fortunately, most bugs that were first present when it was first made available have been weeded out, and this version of Windows 10 is far more stable.

That being said, you should upgrade to this version as soon as possible if your hardware allows it (the system requirements are the same as with Windows 10 v2004).

If you haven’t updated to Windows 10 v20H2, know that it is easiest to update if you already have Windows 10 v2004. Check out this in-depth guide on how to get Windows 10 v20H2 as fast as possible.

Cumulative update name:

Improvements and fixes:

  • Addresses a possible elevation of privilege vulnerability in the win32k component.
  • Addresses an issue that might damage the file system of some devices and prevent them from starting up after running chkdsk /f.
  • Security updates to the Windows App Platform and Frameworks, Windows Apps, Windows Input and Composition, Windows Cloud Infrastructure, Windows Management, Windows Authentication, Windows Fundamentals, Windows Cryptography, Windows Virtualization, Windows Core Networking, and Windows Hybrid Cloud Networking.

Known Issues:

  • System and user certificates might be lost when updating a device from Windows 10, version 1809 or later to a later version of Windows 10. Devices will only be impacted if they have already installed any Latest cumulative update (LCU) released September 16, 2020 or later and then proceed to update to a later version of Windows 10 from media or an installation source which does not have an LCU released October 13, 2020 or later integrated. This primarily happens when managed devices are updated using outdated bundles or media through an update management tool such as Windows Server Update Services (WSUS) or Microsoft Endpoint Configuration Manager. This might also happen when using outdated physical media or ISO images that do not have the latest updates integrated.
    • Note Devices using Windows Update for Business or that connect directly to Windows Update are not impacted. Any device connecting to Windows Update should always receive the latest versions of the feature update, including the latest LCU, without any extra steps.
  • When using the Microsoft Japanese Input Method Editor (IME) to enter Kanji characters in an app that automatically allows the input of Furigana characters, you might not get the correct Furigana characters. You might need to enter the Furigana characters manually.
    • Note The affected apps are using the ImmGetCompositionString() function.
  • Microsoft and Discord have found incompatibility issues with some games using Direct3D 12 when the in-game overlay feature of Discord is enabled. When attempting to open affected games you might receive an error, or the game might close silently.

This wraps up our brief overview of this month’s Patch Tuesday updates, and we hope that by reading the changelogs above, you will make a more informed decision regarding whether to update or not.

However, keep in mind that if you choose not to update for too long, you will risk exposing yourself to subsequent malware attacks that usually follow the Patch Tuesday updates, called Exploit Wednesday.

However, if you do prefer to wait out until Microsoft fixes the issues detected in this month’s updates, know that you can always choose to delay the Update notification that you get for up to 35 days.

All in all, it is important to remember that the Patch Tuesday updates are released for a reason, so installing them, eventually, is something that you should do.
