Changes included in the November Patch Tuesday Updates

Windows 10, version 20H2

Windows 10 v20H2 is the latest major version of Windows 10, and as such has the most experimental features on it. That being the case you should install this version as soon as possible if your hardware allows it.

Take note that Windows 10 v2009’s system requirements aren’t that high, so don’t worry about compatibility issues.

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 security vulnerability by preventing applications that run as a SYSTEM account from printing to FILE: ports. To address this issue in the future, make sure your applications or services run as a specific user or service account.
  • Security updates to Microsoft Edge Legacy, the Microsoft Graphics Component, Windows Media, Windows Fundamentals, and Windows Virtualization.

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 This primarily happens when managed devices are updated using outdated bundles or media through an update management tool such as Windows Server Update Services (WSUS) or Microsoft Endpoint Configuration Manager. This might also happen when using outdated physical media or ISO images that do not have the latest updates integrated.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.
