Windows 11 KB5034204 Brings Back 3D Emojis, Fixes Bluetooth Connectivity & Start Menu

Windows 11 Cumulative UpdateWindows 11 Cumulative Update

The preview update KB5034204 has been rolled out for Windows 11 users. This optional non-security update must be installed manually from Windows Settings or using the direct download links provided below.

This update is available for both Windows 11 22H2 and 23H2 users, and after installing KB5034204, the builds will be upgraded to 22621.3085 and 22631.3085, respectively.

This update does not include any significant new features and no security improvements; mostly a ton of bug fixes. However, one fix affecting the color font format for COLRv1 restores the 3D emojis that were once there but could not be used because of the bug.

Additionally, this update also includes fixes for Bluetooth connectivity, File Explorer, the Start menu, and many others.

What’s new in KB5034204

KB5034204 includes a total of 29 bug fixes. I have highlighted the important ones here:

  • The update addresses a known issue that affects the color font format for COLRv1. It now renders properly. Windows uses this format to display emoji with a 3D-like appearance.
  • This update addresses an issue that causes your device to shut down after 60 seconds. This occurs when you use a smart card to authenticate on a remote system.
  • This update addresses an issue that stops search from working on the Start menu for some users. The issue occurs because of a deadlock.
  • This update addresses an issue that makes the troubleshooting process fail. This occurs when you use the Get Help app.
  • This update addresses an issue that affects the File Explorer Gallery. It stops you from closing a tooltip.
  • This update addresses an issue that affects certain types of 7-Zip files. They appear as empty in File Explorer.
  • This update makes Windows more reliable during power transitions. This reduces the risk of a stop error.
  • This update addresses an issue that affects Bluetooth Low Energy (LE) Audio earbuds. They lose sound when you stream music.
  • This update addresses an issue that affects a Bluetooth phone call. It stops the audio from routing through the PC when you answer the call on your PC.
  • This update addresses an issue that affects Trusted Platform Modules (TPM). On certain devices, they did not initialize correctly. Because of this, TPM-based scenarios stopped working.
  • This update addresses an issue that affects a remote desktop client. It might connect to a wrong instance of a user’s session. This occurs if a user has multiple sessions on the host.

If you were affected by any of these existing bugs, take solace in the fact that these are now fixed, as long as you install the optional KB5034204 update.

Known issues in KB5034204

With these improvements, there is one issue with it as well that has existed in all Windows 11 updates for a while now.

When you open Windows Copilot, the desktop icons get randomly rearranged with no sorting order and spread across the screen. This issue only occurs with systems in a multimonitor setup. You can take solace in the fact that the icons are reverted to their original places when you close Copilot.

At the moment, there is no workaround for this issue. However, Microsoft has disabled Copilot in Preview on devices that have been using a multi-monitor configuration.

KB5034204 File Explorer error

There are reports of users experiencing an “explorer.exe” error when restarting or shutting down the PC after installing KB5034204. More specifically, multiple users are seeing the following error message:

The instruction at 0x00007FFEB25C3ACA referenced memory at 0x0000000000000024. The memory could not be written.

This issue occurs because of inadequately configured graphics software, out-of-date graphics drivers, corrupted system files, a transient memory malfunction, corrupted files, interference from outside services, or hardware problems that can also cause it.

Note that not a lot of people are experiencing this issue, and some that are, were able to fix it after disconnecting certain hardware peripherals. For example, a user was reportedly able to solve the error after disconnecting their Xbox 360 controllers.
