You are here, which means you are surely keeping up with everything that happens with Microsoft’s latest operating system, Windows 11.

Lately, we’ve presented the latest Dev Channel Insider Preview Build 25252, and also KB5020035, which was intended for Beta Channel Insiders.

Today, however, it is time to talk about KB5020044 and all the benefits it brings to Windows 11 version 22H2 users.

We will also add the full changelog, so you can get a better idea of what Microsoft has changed and tweaked via this cumulative update.

Build 22621.900 is packed with bug fixes

Indeed, Microsoft has released its new Windows 11 KB5020044 update (build 22621.900) and it is probably one of the biggest updates we received in quite a while.

This latest cumulative update finally fixes the gaming performance issues that have plagued Windows 11 22H2 ever since its release.

Furthermore, the new update also brings features that we are expecting with the Moment 2 release, just in case you didn’t know.

And, speaking of Moment updates, it looks like the development of Moment 4 may already be underway according to internal test IDs.

You should also know that users who have picked Dark or Light mode in the Settings app shouldn’t be impacted by the Task Manager display bug that comes with KB5020044, according to Microsoft.

You will find information about this problem in the Known issues category of the article. Microsoft is currently working on a fix to address this known issue and says it will provide an update in an upcoming release.

That being said, until a resolution is available, the tech giant has provided a temporary solution that should mitigate the issue on impacted systems.

To workaround this annoying bug, you are required to choose either Dark or Light for the Choose your mode setting.

Before we get into the changelog, know that this non-security update also fixes an issue linked to GPU performance debugging features that affect some games and applications’ performance.

Known issues

  • Using provisioning packages on Windows 11, version 22H2 (also called Windows 11 2022 Update) might not work as expected. Windows might only be partially configured, and the Out Of Box Experience might not finish or might restart unexpectedly. Provisioning packages are .PPKG files which are used to help configure new devices for use on business or school networks. Provisioning packages which are applied during initial setup are most likely to be impacted by this issue. For more information on provisioning packages, please see Provisioning packages for Windows.
  • Copying large multiple gigabyte (GB) files might take longer than expected to finish on Windows 11, version 22H2. You are more likely to experience this issue copying files to Windows 11, version 22H2 from a network share via Server Message Block (SMB) but local file copy might also be affected. Windows devices used by consumers in their home or small offices are not likely to be affected by this issue.
  • After installing this update, Task Manager might display certain elements in the user interface (UI) in unexpected colors. On affected devices, Task Manager should function as expected, but some parts of the UI might not be readable. You might be affected by this issue if you have “Choose your mode” set to Custom in the Personalization > Colors section of Settings. If you are using Dark or Light for the Choose your mode setting, you should not be affected by this issue.
