Windows 10 KB5004296 Rolled Out For v2004, v20H2, and v21H1, Solving Gaming Issues

As a part of the monthly cumulative updates, Microsoft has released the security patches for the month of December 2020. These don’t include any new features, but fixes for bugs for known security vulnerabilities. And the update is available for a range of Windows 10 versions including the latest October 2020 version.

Patching Bugs in Windows 10

Here is the list of an available update to all eligible Windows 10 versions;

Since these are security patches, they will be automatically updated based on the user’s version of Windows 10. If you want to stay out of this update since Microsoft is having a rough time lately with its cumulative updates since the beginning of the year, click Pause.

To do this, head onto Settings and into Update & Security. Here, you’ll see the available updates for your system.  Talking about the changes in the October 2020 update, Microsoft has detailed them all in the table below;

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 This primarily happens when managed devices are updated using outdated bundles or media through an update management tool such as Windows Server Update Services (WSUS) or Microsoft Endpoint Configuration Manager. This might also happen when using outdated physical media or ISO images that do not have the latest updates integrated.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

If you have already encountered this issue on your device, you can mitigate it within the uninstall window by going back to your previous version of Windows using the instructions here. The uninstall window might be 10 or 30 days depending on the configuration of your environment and the version you’re updating to. You will then need to update to the later version of Windows 10 after the issue is resolved in your environment. Note Within the uninstall window, you can increase the number of days you have to go back to your previous version of Windows 10 by using the DISM command /Set-OSUninstallWindow. You must make this change before the default uninstall window has lapsed. For more information, see DISM operating system uninstall command-line options.

We are working on a resolution and will provide updated bundles and refreshed media in the coming weeks.

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.

We are working on a resolution and will provide an update in an upcoming release.
